CVE-2026-66145: CWE-94 Improper Control of Generation of Code ('Code Injection') in SonicWall GMS
CVE-2026-66145 is a high-severity vulnerability in SonicWall GMS versions 9.5.1 (Build 9510.1044) and earlier. It allows an unauthenticated remote attacker to perform remote code execution by exploiting a zip slip vulnerability, enabling arbitrary file writes and sensitive data access.
AI Analysis
Technical Summary
This vulnerability (CWE-94) in SonicWall GMS involves improper control of code generation, specifically a zip slip vulnerability that permits unauthenticated remote attackers to write arbitrary files and read sensitive data. The affected versions include GMS 9.5.1 (Build 9510.1044) and earlier. The CVSS 3.1 score is 8.3, indicating high severity, with attack vector as adjacent network, high attack complexity, no privileges required, no user interaction, and impacts on confidentiality, integrity, and availability. No official patch or remediation guidance is currently available, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary code, read sensitive data, and write files arbitrarily on affected SonicWall GMS systems. This compromises confidentiality, integrity, and availability of the system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to the affected GMS instances and monitor for suspicious activity related to file uploads or zip processing.
