CVE-2023-34135
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedPath Traversal vulnerability in SonicWall GMS and Analytics allows a remote authenticated attacker to read arbitrary files from the underlying file system via web service. This issue affects GMS: 9.3.2-SP1 and earlier versions; Analytics: 2.5.0.4-R7 and earlier versions.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidencePath traversal vulnerability in SonicWall GMS and Analytics web services allows authenticated remote attackers to read arbitrary files from the filesystem by manipulating path traversal sequences (e.g., ../) in web service parameters.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check SonicWall GMS versionLog into the GMS admin console and navigate to Help > About, or run 'show version' via CLI if availableAffected if Version is less than 9.3.2 (e.g., 9.3.1, 9.3.0, earlier) or equals exactly 9.3.2
-
Check SonicWall Analytics versionLog into the Analytics admin console and navigate to Help > About, or check the installation directory for version metadataAffected if Version is 2.5.0.4-r7 or earlier (e.g., 2.5.0.4-r6, 2.5.0.3, earlier)
-
Verify web service accessibilityConfirm the GMS or Analytics web interface is exposed externally or accessible to untrusted users. Check firewall rules and reverse proxy configurations for port 443/8080 access listsAffected if Web services are reachable from untrusted networks without VPN or IP restriction
-
Inspect web server logs for path traversal patternsSearch access logs (typically in /var/log/httpd/, /opt/sonicwall/analytics/logs/, or GMS logs directory) for strings containing '../' or '..%2F' in request parametersAffected if Logs show anomalous path traversal requests that your organization did not intentionally make
-
Check for unauthorized file access attemptsReview application and audit logs for successful file retrieval operations, especially accessing system files like /etc/passwd, configuration files, or database files outside the application rootAffected if Log entries indicate file reads from unexpected filesystem locations
You are affected if you run GMS version 9.3.2 or below, or Analytics version 2.5.0.4-r7 or below, and your web services are accessible to attackers who can send path traversal sequences in requests.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped9.3.2
Apply vendor-supplied patches for GMS 9.3.2-SP1 and earlier and Analytics 2.5.0.4-R7 and earlier; until patched, restrict web service access to trusted users and implement web application firewall rules to detect and block path traversal patterns.
GMS: 9.3.2-SP2 or later; Analytics: 2.5.0.4-R8 or later
- 1. Identify the currently installed SonicWall GMS and/or Analytics version via the web management interface or system information
- 2. For GMS: Upgrade to version 9.3.2-SP2 or later to resolve the path traversal vulnerability
- 3. For Analytics: Upgrade to version 2.5.0.4-R8 or later to resolve the path traversal vulnerability
- 4. After upgrade, verify the installation was successful and the web services are functioning normally
- 5. Confirm the vulnerability is remediated by reviewing release notes or consulting SonicWall support if needed
