[salt-users] 20181024 2018.3.3 Released - Security Advisory

[debian-lts-announce] 20200728 [SECURITY] [DLA 2294-1] salt security update

USN-4459-1

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:2106-1 advisory.

  - Directory Traversal vulnerability in salt-api in SaltStack Salt before 2017.7.8 and 2018.3.x before     2018.3.3 allows remote attackers to determine which files exist on the server. (CVE-2018-15750)

  - SaltStack Salt before 2017.7.8 and 2018.3.x before 2018.3.3 allow remote attackers to bypass     authentication and execute arbitrary commands via salt-api(netapi). (CVE-2018-15751)

  - An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process     ClearFuncs class does not properly validate method calls. This allows a remote user to access some methods     without authentication. These methods can be used to retrieve user tokens from the salt master and/or run     arbitrary commands on salt minions. (CVE-2020-11651)

  - An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process     ClearFuncs class allows access to some methods that improperly sanitize paths. These methods allow     arbitrary directory access to authenticated users. (CVE-2020-11652)

  - In SaltStack Salt through 3002, salt-netapi improperly validates eauth credentials and tokens. A user can     bypass authentication and invoke Salt SSH. (CVE-2020-25592)

  - A Incorrect Implementation of Authentication Algorithm vulnerability in of SUSE SUSE Linux Enterprise     Server 15 SP 3; openSUSE Tumbleweed allows local attackers to execute arbitrary code via salt without the     need to specify valid credentials. This issue affects: SUSE SUSE Linux Enterprise Server 15 SP 3 salt     versions prior to 3002.2-3. openSUSE Tumbleweed salt version 3002.2-2.1 and prior versions.
    (CVE-2021-25315)

  - 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 has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:0899-1 advisory.

  - Directory Traversal vulnerability in salt-api in SaltStack Salt before 2017.7.8 and 2018.3.x before     2018.3.3 allows remote attackers to determine which files exist on the server. (CVE-2018-15750)

    (CVE-2021-25315)

  - 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.

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

It was discovered that Salt allows remote attackers to determine which files exist on the server. An attacker could use that to extract sensitive information. (CVE-2018-15750) It was discovered that Salt has a vulnerability that allows an user to bypass authentication. An attacker could use that to extract sensitive information, execute abritrary code or crash the server. (CVE-2018-15751) It was discovered that Salt is vulnerable to command injection. This allows an unauthenticated attacker with network access to the API endpoint to execute arbitrary code on the salt-api host. (CVE-2019-17361) It was discovered that Salt incorrectly validated method calls and sanitized paths. A remote attacker could possibly use this issue to access some methods without authentication. (CVE-2020-11651, CVE-2020-11652).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Two issues have been found in salt, a remote manager to administer servers.

These issues are related to remote hackers bypassing authentication to execute arbitrary commands and getting informations about files on the server

For Debian 9 stretch, these problems have been fixed in version 2016.11.2+ds-1+deb9u5.

We recommend that you upgrade your salt packages.
