EUVDB-ID: #VU56000
Risk: Medium
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-3621
CWE-ID:
CWE-77 - Command injection
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper input validation in the sssctl command within the logs-fetch and cache-expire subcommands. An attacker can trick the root user into running a specially crafted sssctl command, such as via sudo, and execute arbitrary code with root privileges.
Update the affected package sssd to the latest version.
