Summary

CVE-2024-34102 is a critical-severity Improper Restriction of XML External Entity Reference (CWE-611) vulnerability in Adobe Commerce. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); 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 map to CM-6 (Configuration Settings) and SA-11 (Developer Testing and Evaluation) — 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.

Adobe Commerce versions 2.4.7, 2.4.6-p5, 2.4.5-p7, 2.4.4-p8 and earlier contain an XXE vulnerability (CWE-611) that permits arbitrary code execution. The flaw stems from improper restriction of XML external entity references and carries a CVSS 3.1 score of 9.8, reflecting network-accessible attack vectors that require no authentication or user interaction.

An unauthenticated attacker can send a crafted XML document containing malicious external-entity references directly to the affected application, resulting in full compromise of confidentiality, integrity, and availability. Exploitation does not depend on any prior foothold or victim action.

Adobe’s APSB24-40 advisory addresses the issue, and the vulnerability appears in CISA’s Known Exploited Vulnerabilities catalog. The associated EPSS score has reached a peak of 0.9733 with a current value of 0.9417, indicating sustained and substantial exploitation interest following disclosure.
