A misconfiguration in the AndroidManifest.xml file in hamza417/inure before build97 allows for task hijacking. This vulnerability permits malicious applications to inherit permissions of the vulnerable app, potentially leading to the exposure of sensitive information. An attacker can create a malicious app that hijacks the legitimate Inure app, intercepting and stealing sensitive information when installed on the victims device. This issue affects all Android versions before Android 11.
Weakness
During installation, installed file permissions are set to allow anyone to modify those files.
Potential Mitigations
- Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
