Published: 13 July 2023
Summary
CVE-2023-34124 is a critical-severity Authentication Bypass by Primary Weakness (CWE-305) vulnerability in Sonicwall Global Management System. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 0.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
The vulnerability CVE-2023-34124 is an authentication bypass in the web services authentication mechanism of SonicWall GMS and Analytics, caused by insufficient checks. It affects GMS versions 9.3.2-SP1 and earlier as well as Analytics versions 2.5.0.4-R7 and earlier, and is associated with CWE-305 and CWE-287. The flaw received a CVSS 3.1 score of 9.8 reflecting network-accessible attack conditions with no prerequisites.
Unauthenticated remote attackers can exploit the weakness to bypass authentication entirely and obtain full read, write, and control capabilities over the affected components. Public exploit references describe resulting remote code execution paths once the bypass succeeds.
SonicWall published advisory SNWLID-2023-0010 and related support notices directing customers to apply available updates. The EPSS score reached 0.9132, indicating substantial post-disclosure exploitation interest.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Detects unauthorized successful logons resulting from improper authentication implementations.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
Security awareness training instructs users on secure authentication practices and avoiding credential compromise.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.
Session content review can reveal authentication bypasses or failures in session establishment.
Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
