Detailsinfo

A vulnerability has been found in com.basecamp.bc3 up to 4.2.0 on Android (Android App Software) and classified as critical. This vulnerability affects an unknown code of the component Deeplink Scheme Handler. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Directory traversal can occur in the Basecamp com.basecamp.bc3 application before 4.2.1 for Android, which may allow an attacker to write arbitrary files in the application's private directory. Additionally, by using a malicious intent, the attacker may redirect the server's responses (containing sensitive information) to third-party applications by using a custom-crafted deeplink scheme.
