CVE-2023-6343
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 · uneditedTyler Technologies Court Case Management Plus allows a remote, unauthenticated attacker to enumerate and access sensitive files using the tiffserver/tssp.aspx 'FN' and 'PN' parameters. This behavior is related to the use of a deprecated version of Aquaforest TIFF Server, possibly 2.x. The vulnerable Aquaforest TIFF Server feature was removed on or around 2023-11-01. Insecure configuration issues in Aquaforest TIFF Server are identified separately as CVE-2023-6352. CVE-2023-6343 is similar to CVE-2020-9323. CVE-2023-6343 is related to or partially caused by CVE-2023-6352.
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 · high confidenceTyler Technologies Court Case Management Plus contains a path traversal/file enumeration vulnerability in the Aquaforest TIFF Server component (tssp.aspx endpoint). A remote, unauthenticated attacker can access sensitive files via the 'FN' and 'PN' parameters. The vulnerable feature was removed in updates released around November 2023.

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.
-
Verify if tssp.aspx endpoint is accessibleAttempt to access the URL path /tiffserver/tssp.aspx on your Tylertech Court Case Management Plus server. Use a web browser or curl command: curl -I https://<your-server>/tiffserver/tssp.aspxAffected if The endpoint returns an HTTP 200 or any successful response rather than a 404 or access denied error, indicating the vulnerable feature is present
-
Test FN parameter for path traversalSend a request to tssp.aspx with the FN parameter pointing to a known file outside the expected directory, for example: /tiffserver/tssp.aspx?FN=../../../../windows/win.ini or /tiffserver/tssp.aspx?FN=/etc/passwdAffected if The response returns contents of files outside the intended TIFF directory, confirming the path traversal vulnerability is exploitable
-
Test PN parameter for file enumerationSend a request to tssp.aspx with the PN parameter to enumerate directory contents, for example: /tiffserver/tssp.aspx?PN=../../Affected if The response reveals file listings or directory contents that should not be accessible, confirming file enumeration is possible
-
Confirm vulnerable component presenceCheck if the /tiffserver/ directory and tssp.aspx file exist in the web root of your Tylertech installation. Inspect the application's web.xml or equivalent routing configuration for the tssp.aspx handler.Affected if The tssp.aspx handler is registered and the physical file exists in the deployment, meaning the vulnerable Aquaforest TIFF Server component is installed
-
Verify patch status via endpoint removalAfter applying the November 2023 update, re-attempt access to /tiffserver/tssp.aspxAffected if The endpoint is still accessible after applying the update, indicating the patch was not successfully applied or the vulnerable feature was not removed
Your environment is affected if the /tiffserver/tssp.aspx endpoint is accessible and the FN or PN parameters allow reading files or listing directories outside the intended TIFF storage directory.

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 · scopedApply the Aquaforest TIFF Server patch or Tyler Technologies update released on or after 2023-11-01 which removes the vulnerable TIFF server feature. Verify the tiffserver/tssp.aspx endpoint is no longer accessible.
Court Case Management Plus version released after November 2023 (contact Tyler Technologies for exact version number)
- Contact Tyler Technologies to obtain the Court Case Management Plus version released after November 2023 that includes the removal of the vulnerable Aquaforest TIFF Server feature
- Verify with Tyler Technologies that the upgrade includes the fix for CVE-2023-6343 (removal of tiffserver/tssp.aspx FN/PN parameter vulnerability)
- After upgrading, confirm that the tiffserver/tssp.aspx endpoint no longer allows unauthenticated access to sensitive files
- Review system logs to ensure no prior compromise occurred during the vulnerable period
