CVE-2022-37705: A privilege escalation flaw was found in Amanda 3.5.1 in which the backup user can acquire root privileges.

A privilege escalation flaw was found in Amanda 3.5.1 in which the backup user can acquire root privileges. The vulnerable component is the runtar SUID program, which is a wrapper to run /usr/bin/tar with specific arguments that are controllable by the attacker. This program mishandles the arguments passed to tar binary (it expects that the argument name and value are separated with a space; however, separating them with an equals sign is also supported),

Security readout for executives and security teams

CVE-2022-37705 is a local privilege escalation in Amanda 3.5.1. A user with the backup account can abuse the SUID runtar wrapper to gain root privileges. This matters most on backup servers, where root compromise can expose backup data and recovery infrastructure. Exposure is most likely on Unix-like systems running Amanda 3.5.1 with the runtar SUID helper installed and accessible to the backup user. Fedora and Debian advisories indicate distribution package updates existed, but the source bundle does not provide a complete affected-version matrix. Prioritize backup servers because successful exploitation can convert limited backup-user access into root control. Address during the next urgent maintenance window, sooner if Amanda hosts are internet-adjacent, shared, or have many administrative users. Mitigation focus: Check vendor or distribution advisories for Amanda package updates.; Upgrade Amanda to a fixed vendor-supported release when available.; Review Amanda community release 3.5.3 for relevant fixes..
