high Nessus Plugin ID 155282

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the sssd packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs- fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root access. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3621)

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