CVE-2022-3560 is a path traversal vulnerability in the pesign package, affecting Fedora and Red Hat Enterprise Linux. The flaw arises because the pesign systemd service script, which sets ACLs for specific directories, fails to check for symbolic links. This oversight could allow a local attacker to gain unauthorized access to privileged files and directories. Rated with a CVSS score of 5.5 (MEDIUM), this vulnerability has a low attack complexity and requires local privileges, but could lead to high confidentiality impact. The EPSS score is very low, suggesting a minimal probability of exploitation. Currently, there is no known active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE. It is not listed in CISA's KEV catalog.

A flaw was found in pesign. The pesign package provides a systemd service used to start the pesign daemon. This service unit runs a script to set ACLs for /etc/pki/pesign and /run/pesign directories to grant access privileges to users in the 'pesign' group. However, the script doesn't check for symbolic links. This could allow an attacker to gain access to privileged files and directories via a path traversal attack.
