GFI Archiver MArc.Core Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GFI Archiver. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the configuration of the MArc.Core.Remoting.exe process, which listens on port 8017. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-27935.
AnalysisAI
Unsafe deserialization in GFI Archiver's MArc.Core.Remoting service (port 8017) enables authenticated remote attackers to achieve unauthenticated remote code execution with SYSTEM privileges, despite the authentication requirement being bypassable. The vulnerability stems from insufficient validation of untrusted data during the deserialization process, allowing arbitrary code execution on affected systems. …
