6.7 MediumPublic exploitFix available

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),

amanda security update

AMANDA, the Advanced Maryland Automatic Network Disk Archiver, is a backup system that allows the administrator of a LAN to set up a single master backup server to back up multiple hosts to a single large capacity tape or disk drive. Amanda uses native tools (such as GNUtar, dump) for backup and can back up a large number of workstations running multiple versions of Unix/Mac OS X/Linux/Windows.

Security Fix(es):

A flaw was found in Amanda. The runtar SUID binary executes /usr/bin/tar as root without properly validating its arguments, possibly leading to escalation of privileges from the regular user "amandabackup" to root.(CVE-2022-37705)

A flaw was found in Amanda. The rundump SUID binary executes /usr/sbin/dump as root without properly validating its arguments, possibly leading to escalation of privileges from the regular user "amandabackup" to root.(CVE-2022-37704)
