On Wednesday, July 12, 2023, security firm SonicWall published an urgent security advisory warning customers of 15 new vulnerabilities affecting on-premise instances of their Global Management System (GMS) and Analytics products. Four of the vulnerabilities carry critical severity ratings:

  • CVE-2023-34124: Web service authentication bypass
  • CVE-2023-34133: Multiple unauthenticated SQL injection issues and security filter bypass
  • CVE-2023-34134: Password hash read via web service
  • CVE-2023-34137: CAS authentication bypass

The rest of the vulnerabilities include a predictable password reset key issue and a hard-coded Tomcat credentials issue, in addition to command injection, file write, file upload, password hash read, and other issues. SonicWall took the unusual (but not unprecedented) step of issuing an urgent security notice for the new CVEs.

Per the company’s advisory, the various vulnerabilities could allow an attacker to view data that they would not normally be able to retrieve, including data belonging to other users or other data that the application itself is able to access. Attackers may be able to modify or delete this data, causing persistent changes to the application's content or behavior. At least on the surface, the potential for data exposure and theft as a result of these flaws sounds reminiscent of the recent MOVEit Transfer vulnerabilities — we expect these CVEs to be extremely attractive to adversaries, including those looking to extort victims after executing smash-and-grab attacks.

While the vulnerabilities are not known to be exploited in the wild as of July 13, 2023, SonicWall vulnerabilities, including Rapid7-discovered vulnerabilities, have been popular targets for adversaries in the past (including ransomware groups). The urgent nature of SonicWall’s warning reflects that history and should be heeded.

Mitigation guidance

The affected products are:

  • SonicWall GMS 9.3.2-SP1 and before
  • SonicWall Analytics and before

The vulnerabilities are fixed in SonicWall GMS 9.3.3 and SonicWall Analytics 2.5.2. We urge on-prem customers to update immediately, without waiting for a regular patch cycle to occur. See SonicWall’s advisory for full details.

Rapid7 customers

Vulnerability checks for the four critical CVEs in SonicWall GMS are available to InsightVM and Nexpose customers as of the July 13 content release. Vulnerability checks for the remaining 11 CVEs affecting SonicWall GMS are expected to be available in the July 14 content release. We are investigating the feasibility of adding checks for SonicWall Analytics.
