Summary

CVE-2024-2053 is a high-severity Relative Path Traversal (CWE-23) vulnerability in Articatech Artica Proxy. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The vulnerability CVE-2024-2053 affects the Artica Proxy administrative web application, specifically version 4.50. It stems from the application's deserialization of arbitrary PHP objects supplied by unauthenticated users, which leads to code execution as the www-data user. The component also attempts to block local file inclusion, but these controls can be bypassed to permit arbitrary file requests returned under www-data privileges. The issue carries a CVSS 3.1 score of 7.5 reflecting network attack vector, low complexity, no required privileges or user interaction, and high confidentiality impact.

Unauthenticated remote attackers can supply malicious serialized objects or file paths directly to the administrative web interface. Successful exploitation grants the ability to execute code or read arbitrary files on the server with the privileges of the www-data account, enabling disclosure of sensitive configuration or data without authentication.

Public advisories published via KoreLogic and Seclists in March 2024 document the deserialization and path traversal flaws but do not detail available patches or configuration workarounds in the referenced materials.

The EPSS probability rose to a peak of 0.4086 before settling at the current value of 0.3654, indicating that exploitation interest increased after public disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Explicit validation of path inputs stops .. sequences from ever being interpreted by the file system.

Access enforcement directly blocks unauthorized file reads/writes that result from unresolved .. sequences.

Information-flow rules can be configured to reject traversals that would move data outside an approved directory boundary.

Least privilege reduces the set of reachable files even when a traversal succeeds.

Secure-engineering principles require safe pathname construction and input neutralization before any file operation.

finds

Security testing in development catches path traversal via static/dynamic analysis, but does not itself implement the fix.

prevents

Secure development lifecycle mandates input validation and path-handling controls that directly prevent relative path traversal.

prevents

Application security requirements explicitly call for controls against path traversal and other injection flaws.

prevents

Secure architecture principles include directory isolation and canonicalization, reducing but not eliminating traversal risk.

prevents

Secure coding standards require neutralizing path traversal sequences, directly addressing CWE-23.

mitigates

Information access restriction limits which files can be reached, mitigating impact but not preventing the traversal flaw.
