An issue was discovered in SaltStack Salt before 3003.3. A user who has control of the source, and source_hash URLs can gain full file system access as root on a salt minion.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An issue was discovered in SaltStack Salt before 3003.3. A user who has control of the source, and     source_hash URLs can gain full file system access as root on a salt minion. (CVE-2021-21996)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote host is affected by the vulnerability described in GLSA-202310-22 (Salt: Multiple Vulnerabilities)

  - An issue was discovered in SaltStack Salt before 3002.5. The minion's restartcheck is vulnerable to     command injection via a crafted process name. This allows for a local privilege escalation by any user     able to create a files on the minion in a non-blacklisted directory. (CVE-2020-28243)

  - In SaltStack Salt before 3002.5, authentication to VMware vcenter, vsphere, and esxi servers (in the     vmware.py files) does not always validate the SSL/TLS certificate. (CVE-2020-28972)

  - In SaltStack Salt before 3002.5, when authenticating to services using certain modules, the SSL     certificate is not always validated. (CVE-2020-35662)

  - In SaltStack Salt before 3002.5, eauth tokens can be used once after expiration. (They might be used to     run command against the salt master or minions.) (CVE-2021-3144)

  - An issue was discovered in SaltStack Salt before 3002.5. Sending crafted web requests to the Salt API can     result in salt.utils.thin.gen_thin() command injection because of different handling of single versus     double quotes. This is related to salt/utils/thin.py. (CVE-2021-3148)

  - An issue was discovered in SaltStack Salt before 3002.5. The salt-api's ssh client is vulnerable to a     shell injection by including ProxyCommand in an argument, or via ssh_options provided in an API request.
    (CVE-2021-3197)

  - An issue was discovered in SaltStack Salt before 3003.3. A user who has control of the source, and     source_hash URLs can gain full file system access as root on a salt minion. (CVE-2021-21996)

  - An issue was discovered in through SaltStack Salt before 3002.5. salt-api does not honor eauth credentials     for the wheel_async client. Thus, an attacker can remotely run any wheel modules on the master.
    (CVE-2021-25281)

  - An issue was discovered in through SaltStack Salt before 3002.5. The salt.wheel.pillar_roots.write method     is vulnerable to directory traversal. (CVE-2021-25282)

  - An issue was discovered in through SaltStack Salt before 3002.5. The jinja renderer does not protect     against server side template injection attacks. (CVE-2021-25283)

  - An issue was discovered in through SaltStack Salt before 3002.5. salt.modules.cmdmod can log credentials     to the info or error log level. (CVE-2021-25284)

  - In SaltStack Salt 2016.9 through 3002.6, a command injection vulnerability exists in the snapper module     that allows for local privilege escalation on a minion. The attack requires that a file is created with a     pathname that is backed up by snapper, and that the master calls the snapper.diff function (which executes     popen unsafely). (CVE-2021-31607)

  - An issue was discovered in SaltStack Salt in versions before 3002.8, 3003.4, 3004.1. Salt Masters do not     sign pillar data with the minion's public key, which can result in attackers substituting arbitrary pillar     data. (CVE-2022-22934)

  - An issue was discovered in SaltStack Salt in versions before 3002.8, 3003.4, 3004.1. A minion     authentication denial of service can cause a MiTM attacker to force a minion process to stop by     impersonating a master. (CVE-2022-22935)

  - An issue was discovered in SaltStack Salt in versions before 3002.8, 3003.4, 3004.1. Job publishes and     file server replies are susceptible to replay attacks, which can result in an attacker replaying job     publishes causing minions to run old jobs. File server replies can also be re-played. A sufficient craft     attacker could gain root access on minion under certain scenarios. (CVE-2022-22936)

  - An issue was discovered in SaltStack Salt in versions before 3002.8, 3003.4, 3004.1. When configured as a     Master-of-Masters, with a publisher_acl, if a user configured in the publisher_acl targets any minion     connected to the Syndic, the Salt Master incorrectly interpreted no valid targets as valid, allowing     configured users to target any of the minions connected to the syndic with their configured commands. This     requires a syndic master combined with publisher_acl configured on the Master-of-Masters, allowing users     specified in the publisher_acl to bypass permissions, publishing authorized commands to any configured     minion. (CVE-2022-22941)

  - An issue was discovered in SaltStack Salt in versions before 3002.9, 3003.5, 3004.2. PAM auth fails to     reject locked accounts, which allows a previously authorized user whose account is locked still run Salt     commands when their account is locked. This affects both local shell accounts with an active session and     salt-api users that authenticate via PAM eauth. (CVE-2022-22967)

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.207 advisory.

  - In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

  - The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path,     leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in     /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an     incomplete fix for CVE-2016-10009. (CVE-2023-38408)

  - An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the     attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content     to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing     filenames with two or more newlines where selected content and the target file names are embedded in     crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write     arbitrary files on the system. (CVE-2022-1271)

  - http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5     allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR     and LF control characters in the first argument of HTTPConnection.request. (CVE-2020-26116)

  - urllib3 before 1.25.9 allows CRLF injection if the attacker controls the HTTP request method, as     demonstrated by inserting CR and LF control characters in the first argument of putrequest(). NOTE: this     is similar to CVE-2020-26116. (CVE-2020-26137)

    (CVE-2021-45960)

  - An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0. It     permits the visual reordering of characters via control sequences, which can be used to craft source code     that renders different logic than the logical ordering of tokens ingested by compilers and interpreters.
    Adversaries can leverage this to encode source code for compilers accepting Unicode such that targeted     vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium offers the     following alternative approach to presenting this concern. An issue is noted in the nature of     international text that can affect applications that implement support for The Unicode Standard and the     Unicode Bidirectional Algorithm (all versions). Due to text display behavior when text includes left-to-     right and right-to-left characters, the visual order of tokens may be different from their logical order.
    Additionally, control characters needed to fully support the requirements of bidirectional text can     further obfuscate the logical order of tokens. Unless mitigated, an adversary could craft source code such     that the ordering of tokens perceived by human reviewers does not match what will be processed by a     compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its     document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also     provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode     Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the     BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading     visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.

The version of AOS installed on the remote host is prior to 6.6. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.6 advisory.

  - In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

  - Apache Commons Text performs variable interpolation, allowing properties to be dynamically evaluated and     expanded. The standard format for interpolation is ${prefix:name}, where prefix is used to locate an     instance of org.apache.commons.text.lookup.StringLookup that performs the interpolation. Starting with     version 1.5 and continuing through 1.9, the set of default Lookup instances included interpolators that     could result in arbitrary code execution or contact with remote servers. These lookups are: - script -     execute expressions using the JVM script execution engine (javax.script) - dns - resolve dns records -     url - load values from urls, including from remote servers Applications using the interpolation defaults     in the affected versions may be vulnerable to remote code execution or unintentional contact with remote     servers if untrusted configuration values are used. Users are recommended to upgrade to Apache Commons     Text 1.10.0, which disables the problematic interpolators by default. (CVE-2022-42889)

  - An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the     attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content     to an arbitrary attacker-selected file.

The version of AOS installed on the remote host is prior to 6.0.2.6. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.0.2.6 advisory.

  - CVE-2020-9493 identified a deserialization issue that was present in Apache Chainsaw. Prior to Chainsaw     V2.0 Chainsaw was a component of Apache Log4j 1.2.x where the same issue exists. (CVE-2022-23307)

  - By design, the JDBCAppender in Log4j 1.2.x accepts an SQL statement as a configuration parameter where the     values to be inserted are converters from PatternLayout. The message converter, %m, is likely to always be     included. This allows attackers to manipulate the SQL by entering crafted strings into input fields or     headers of an application that are logged allowing unintended SQL queries to be executed. Note this issue     only affects Log4j 1.x when specifically configured to use the JDBCAppender, which is not the default.
    Beginning in version 2.0-beta8, the JDBCAppender was re-introduced with proper support for parameterized     SQL queries and further customization over the columns written to in logs. Apache Log4j 1.2 reached end of     life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the     previous versions. (CVE-2022-23305)

  - AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS     extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. (CVE-2021-45417)

  - Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data     which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when     listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17.
    (CVE-2019-17571)

  - Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an     SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent     through that appender. Fixed in Apache Log4j 2.12.3 and 2.13.1 (CVE-2020-9488)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for     certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how     they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and     PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and     Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
    (CVE-2021-43527)

  - AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS     extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. (CVE-2021-45417)

  - It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-     default configurations. This could allows attackers with control over Thread Context Map (MDC) input data     when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for     example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input     data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some     environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix     this issue by removing support for message lookup patterns and disabling JNDI functionality by default.

The version of AOS installed on the remote host is prior to 6.1.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.1.1 advisory.

  - JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write     access to the Log4j configuration. The attacker can provide TopicBindingName and     TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result     in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2     when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of     life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the     previous versions. (CVE-2021-4104)

  - It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-     default configurations. This could allows attackers with control over Thread Context Map (MDC) input data     when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for     example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input     data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some     environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix     this issue by removing support for message lookup patterns and disabling JNDI functionality by default.
    (CVE-2021-45046)

  - Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI     features used in configuration, log messages, and parameters do not protect against attacker controlled     LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters     can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From     log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3,     and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to     log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.

  - A flaw was found in OpenLDAP in versions before 2.4.56. This flaw allows an attacker who sends a malicious     packet processed by OpenLDAP to force a failed assertion in csnNormalize23(). The highest threat from this     vulnerability is to system availability. (CVE-2020-25710)

  - A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is     a setuid tool designed to allow unprivileged users to run commands as privileged users according     predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly     and ends trying to execute environment variables as commands. An attacker can leverage this by crafting     environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully     executed the attack can cause a local privilege escalation given unprivileged users administrative rights     on the target machine. (CVE-2021-4034)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its self-reported version number, the instance of SaltStack has a Minion component installed on the remote server and is affected by a remote code execution vulnerability. A remote, unauthorized attacker can trigger this exposure with a carefully crafted payload to gain full file system access as root by injecting malicious code into the full path string.
