Artica Proxy - Path Traversal (CVE-2024-2053)

CVE-2024-2053 is a vulnerability in the Artica Proxy administrative web application that allows unauthenticated attackers to deserialize arbitrary PHP objects, leading to potential remote code execution as the "www-data" user. Additionally, the application's local file inclusion protections can be bypassed, enabling attackers to access arbitrary files on the server. This flaw could be exploited to gain unauthorized access to sensitive data or execute malicious code on affected systems.

CrowdSec has been tracking this vulnerability and its exploits since 21st of January 2026.

According to CrowdSec data, while opportunistic exploitation dominates, a portion of threat actors trying to exploit CVE-2024-2053 apply basic targeting methods such as port or service detection. This indicates emerging patterns of selective targeting. CrowdSec data also reveals a clear uptick in attacks involving CVE-2024-2053 over the past week. Activity is above the usual baseline, suggesting growing attention from attackers. This may reflect rising awareness, recent exploit releases, or expanded targeting efforts.

Attackers exploit the /images.listener.php endpoint by supplying a mailattach parameter with directory traversal sequences (e.g., ..././..././) to access sensitive files on the server without authentication.
