Official Description

PluXml CMS allows a user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behaviour enables an attacker to fix a session ID

for a victim and later hijack the authenticated session.

The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only versions 5.8.21 and 5.9.0-rc7 were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

Risk Analysis

This critical vulnerability in PluXml CMS allows an attacker to fix a user's session ID before authentication and then hijack the authenticated session. With a CVSS score of 9.8, this flaw is highly severe, enabling full control over confidentiality, integrity, and availability, though its exploitation likelihood is currently unknown as no EPSS score is available.

No public exploit is currently known for this vulnerability. The remote attack vector and low attack complexity indicate it is remotely exploitable without authentication.

Recommended Action

To mitigate this vulnerability, ensure PluXml CMS is updated to a version that addresses this session management flaw. Implement proper session management practices, including regenerating session IDs upon authentication.

Technical Analysis

CVE-2026-24352 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
