Adobe Commerce versions 2.4.9-beta1, 2.4.8-p4, 2.4.7-p9, 2.4.6-p14, 2.4.5-p16, 2.4.4-p17 and earlier [NEEDS REVIEW: impact mismatch — ticket says 'Arbitrary file system write', CIA triad derives 'Security Feature Bypass'. Verify CVSS vector before publishing.] are affected by an Improper Input Validation vulnerability that could result in a Security feature bypass. A high-privileged attacker could leverage this vulnerability to bypass security measures and gain unauthorized write access. Exploitation of this issue requires user interaction in that a victim must visit a maliciously crafted URL or interact with a compromised web page. Scope is changed.
AI Analysis
Technical Summary
This vulnerability in Adobe Commerce involves improper input validation (CWE-20) that can be exploited by a high-privileged attacker to bypass security controls and perform unauthorized write operations. Exploitation requires user interaction, such as visiting a crafted URL or interacting with a malicious web page. The vulnerability affects multiple versions including 2.4.9-beta1 and earlier. The CVSS vector indicates network attack vector, low attack complexity, high privileges required, user interaction needed, and a changed scope with no confidentiality or availability impact but low integrity impact. No patch or official remediation level has been published yet.
Potential Impact
An attacker with high privileges can bypass security features and gain unauthorized write access, potentially modifying files or data. The impact on confidentiality and availability is not indicated, but integrity is affected at a low level. Exploitation requires user interaction, limiting the ease of attack. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or temporary mitigation is currently documented, monitor Adobe's advisories for updates. Until a patch is available, limit exposure by restricting high-privileged user access and exercising caution with URLs and web content that users interact with.
