CVE-2026-2039

GFI Archiver MArc.Store Missing Authorization Authentication Bypass Vulnerability. This vulnerability allows remote attackers to bypass authentication on affected installations of GFI Archiver. Authentication is not required to exploit this vulnerability. The specific flaw exists within the configuration of the MArc.Store.Remoting.exe process, which listens on port 8018. The issue results from the lack of authorization prior to allowing access to functionality. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of SYSTEM. Was ZDI-CAN-28597.
