CVE-2026-43975: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Apache Software Foundation Apache Wicket
FolderUploadsFileManager in Apache Wicket does not validate or sanitize the uploadFieldId parameter or the clientFileName before constructing file paths, allowing an unauthenticated attacker to write arbitrary files outside the intended upload directory or read files from arbitrary locations on the server. This issue affects Apache Wicket: from 8.0.0 through 8.17.0, from 9.0.0 through 9.22.0, from 10.0.0 through 10.8.0. Users are recommended to upgrade to version 10.9.0, which fixes the issue.
AI Analysis
Technical Summary
Apache Wicket's FolderUploadsFileManager does not properly validate or sanitize the uploadFieldId parameter or clientFileName before constructing file paths. This improper limitation of a pathname to a restricted directory (CWE-22) enables unauthenticated attackers to perform path traversal attacks, allowing arbitrary file write and read operations outside the designated upload directory. The vulnerability affects multiple versions of Apache Wicket from 8.0.0 up to 10.8.0. The vendor recommends upgrading to version 10.9.0 to fix the issue.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to write arbitrary files outside the intended upload directory or read files from arbitrary locations on the server. This can lead to unauthorized disclosure of sensitive information or unauthorized modification of files on the affected system.
Mitigation Recommendations
Users should upgrade Apache Wicket to version 10.9.0, which fixes this path traversal vulnerability. No other mitigation or temporary fix is indicated. Patch status is confirmed by the vendor's recommendation to upgrade.
