Summary

CVE-2013-2251 is a critical-severity Injection (CWE-74) vulnerability in Apache Archiva. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 0.0% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

Apache Struts versions 2.0.0 through 2.3.15 contain a flaw that allows remote attackers to execute arbitrary OGNL expressions by supplying a parameter containing a crafted action:, redirect:, or redirectAction: prefix. The issue is tracked as CWE-74 and assigned a CVSS 3.1 score of 9.8 reflecting network attack vector, low complexity, and no required privileges or user interaction.

An unauthenticated attacker can therefore submit malicious input to trigger OGNL evaluation, resulting in arbitrary code execution that compromises confidentiality, integrity, and availability of the application server.

Public references list the vulnerability in multiple exploit archives and disclosure lists dating from 2013, confirming the availability of proof-of-concept material.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of all input parameters to reject crafted action:, redirect:, or redirectAction: prefixes before OGNL evaluation occurs.

prevent

Mandates timely application of security patches to eliminate the vulnerable Struts 2.0.0-2.3.15 code paths that permit OGNL injection.

prevent

Enforces information flow rules that can block untrusted parameter values from reaching the OGNL expression evaluator.
