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).

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

  - 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)

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

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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)

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 remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2815 advisory.

    Multiple security vulnerabilities have been discovered in Salt, a powerful remote execution manager, that     allow for local privilege escalation on a minion, server side template injection attacks, insufficient     checks for eauth credentials, shell and command injections or incorrect validation of SSL certificates.
    For Debian 9 stretch, these problems have been fixed in version 2016.11.2+ds-1+deb9u7. We recommend that     you upgrade your salt packages. For the detailed security status of salt please refer to its security     tracker page at: https://security-tracker.debian.org/tracker/salt Further information about Debian LTS     security advisories, how to apply these updates to your system and frequently asked questions can be found     at: https://wiki.debian.org/LTS

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 hosted on the remote server is affected by a command injection vulnerability that may result in privilege escalation. This vulnerability exists in the snapper module and allows for the possibility of 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).
