Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-87: Improper Neutralization of Alternate XSS Syntax, where the product does not neutralize or incorrectly neutralizes user-controlled input for alternate script syntax. In Github.com/forceu/gokapi, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact When using end-to-end encryption, a stored XSS vulnerability can be exploited by uploading a file with JavaScript code embedded in the filename. After upload and every time someone opens the upload list, the script is then parsed. With the affected versions <v2.0, there was no user permission system implemented, therefore all authenticated users were already able to see and modify all resources, even if end-to-end encrypted, as the encryption key had to be the same for all users with <v2.0. Nethertheless with XSS, other attack vectors like redirection or crypto mining would be possble. ### Patches This CVE has been fixed in v2.0.0 ### Workarounds If you are the only authenticated user using Gokapi, you are not affected. A workaround would be to disable end-to-end encryption.
