CVE-2025-9257
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 · uneditedWebITR developed by Uniong has an Arbitrary File Reading vulnerability, allowing remote attackers with regular privileges to exploit Absolute Path Traversal to download arbitrary system files.
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 confidenceWebITR by Uniong contains an arbitrary file reading vulnerability exploitable via absolute path traversal. Authenticated users with regular privileges can manipulate file download requests to provide absolute system paths, bypassing any relative path restrictions and reading sensitive system files outside the webroot.

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.
-
Identify Webitr installation and versionLocate the Webitr installation directory and check version information files, typically found in the application root or version configuration files. Compare the installed version against the affected range: versions prior to 2_1_0_33 are vulnerable.Affected if The installed version is Uniong Webitr and the version number is less than 2_1_0_33
-
Confirm file download functionality existsIdentify the file download module or endpoint in the Webitr application. This is typically accessible via web interface or API and allows authenticated users to request file downloads.Affected if The file download feature is present and accessible to authenticated users with regular (non-admin) privileges
-
Test absolute path handling in download requestsSubmit a download request using an absolute system path (such as /etc/passwd on Linux or C:\Windows\system32\config\sam on Windows) as the file parameter instead of a relative filename. Observe whether the application accepts and processes the absolute path.Affected if The application accepts absolute paths in the download request parameter and returns or attempts to read files outside the intended download directory
-
Check application logs for path traversal attemptsReview Webitr application logs, access logs, or security audit logs for patterns indicating absolute path traversal in download requests. Look for requests containing paths starting with '/' or drive letters.Affected if Logs contain download requests with absolute system paths that were processed by the application
A defender is affected if Uniong Webitr version is below 2_1_0_33 and the file download feature accepts absolute path input, allowing authenticated users to read arbitrary system files.

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 · scoped2_1_0_33
Implement strict input validation that rejects absolute paths and whitelist allowed download directories. Use canonicalization with boundary checking to ensure file paths remain within allowed directories, and disable traversal sequences entirely.
2_1_0_33 or later
- 1. Identify all deployments of WebITR versions prior to 2_1_0_33 in your environment
- 2. Contact Uniong vendor to obtain the fixed version 2_1_0_33 or later
- 3. Schedule a maintenance window for the upgrade
- 4. Backup the current WebITR configuration and data before upgrading
- 5. Apply the upgrade to all affected instances
- 6. Verify the upgrade was successful and test that the path traversal vulnerability is mitigated
- 7. Confirm that legitimate file access functionality still works correctly
