Detailsinfo

A vulnerability was found in Intevation OpenSlides up to 4.2.4. It has been declared as problematic. This vulnerability affects an unknown part of the component Interface. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-24. The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize "../" sequences that can resolve to a location that is outside of that directory. As an impact it is known to affect integrity, and availability. CVE summarizes:

A directory traversal issue was discovered in OpenSlides before 4.2.5. Files can be uploaded to OpenSlides meetings and organized in folders. The interface allows users to download a ZIP archive that contains all files in a folder and its subfolders. If an attacker specifies the title of a file or folder as a relative or absolute path (e.g., ../../../etc/passwd), the ZIP archive generated for download converts that title into a path. Depending on the extraction tool used by the user, this might overwrite files locally outside of the chosen directory.

The advisory is available at x41-dsec.de. This vulnerability was named CVE-2025-30343 since 03/21/2025. The exploitation appears to be difficult. The attack can be initiated remotely. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.
