Detailsinfo

A vulnerability classified as problematic was found in ownCloud App up to 2.x on Android (Android App Software). This vulnerability affects an unknown functionality of the component Internal File Handler. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22.

As an impact it is known to affect confidentiality. CVE summarizes:

The ownCloud Android app allows ownCloud users to access, share, and edit files and folders. Prior to version 3.0, the app has an incomplete fix for a path traversal issue and is vulnerable to two bypass methods.
