## Key facts

- **Exploitation phase:** Limited Exploitation. The vulnerability is known but shows very limited attacker interest or exploitation activity.
- **CVSS score:** 7.5
- **Public exploit available:** Yes
- **Affected products:** Artica Proxy
- **Weaknesses:** CWE-23 (Relative Path Traversal)
- **Tags:** web_application, php

## Description

The Artica Proxy administrative web application will deserialize arbitrary PHP objects supplied by unauthenticated users and subsequently enable code execution as the "www-data" user. This issue was demonstrated on version 4.50 of the The Artica-Proxy administrative web application attempts to prevent local file inclusion. These protections can be bypassed and arbitrary file requests supplied by unauthenticated users will be returned according to the privileges of the "www-data" user.

## CrowdSec analysis

[CVE-2024-2053](https://euvd.enisa.europa.eu/vulnerability/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.
