Vulnerability from fkie_nvd - Published: 2026-07-28 19:17 - Updated: 2026-10-23 23:10
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
Summary
Artica Proxy before 4.50.000000 Service Pack 7 (fixed in hotfix 20260724-02) contains a session fixation vulnerability that allows unauthenticated attackers to hijack administrative sessions by setting a known PHPSESSID on a victim's browser prior to authentication. Attackers can pre-set a controlled session identifier and wait for a victim to authenticate through fw.login.php, after which the attacker gains a fully authenticated administrative session on port 9000.
