Security:

• Various security fixes. See PaperCut NG/MF Security Bulletin (March 2024) for more information. [CDSS-3505], [CDSS-3325], [PO-2080], [PIE-708], [PO-2030]
• This release also includes several pre-emptive security improvements and additions to layers of defense. These improvements were made as a result of code audits, pen tests and security reviews. Changes were made in line with our security uplift initiative.

Fixes:

• Addressed file traversal issues. [CDSS-2495], [PO-1447]
• Hardened internal API Authentication. [PO-1474]
• Updated third party libraries to recommended patch levels. [PO-1441]

Fixes:

• Addressed a Path Traversal vulnerability in the Application Server and Site Server. Under specific conditions, this could potentially allow an attacker read-only access to the server’s file system.  CVE-2023-31046 . [PO-1277]
• Addressed a Cross-Site Request Forgery (CSRF) vulnerability in the Application Server, which, under specific conditions, could potentially enable an attacker to alter security settings or execute arbitrary code. This could be exploited if the target is an admin with a current login session. Exploiting this would typically involve the possibility of deceiving an admin into clicking a specially crafted malicious link, potentially leading to unauthorized changes.  CVE-2023-2533 . [PO-1366]
