Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Path traversal

EUVDB-ID: #VU15544

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-15750

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information.

The vulnerability exists due to insufficient validation of user-supplied input processed by the salt-api component. A remote attacker can send a query request that submits malicious input, conduct directory traversal attack and determine what files exist on the system, and this information can be used to conduct further attacks.

Mitigation

Update the affected package salt to the latest version.

3) Improper Authentication

EUVDB-ID: #VU27494

Risk: Critical

CVSSv4.0: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Red]

CVE-ID: CVE-2020-11651

CWE-ID: CWE-287 - Improper Authentication

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to the salt-master process "ClearFuncs" class does not properly validate method calls. A remote non-authenticated attacker can bypass authentication process and gain 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 minion as root.

Note: this vulnerability is being actively exploited in the wild.

Mitigation

Update the affected package salt to the latest version.
