Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) 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
DescriptionThe 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.
Update the affected package salt to version 2019.2.4-1.
