This vulnerability exists in the `shouldHideDocument` function of the `ExternalStorageProvider.java` file. It occurs due to improper unicode normalization, allowing attackers to bypass the filter meant to restrict access to sensitive directories. This bypass could lead to local privilege escalation, granting unauthorized access to critical system files and functionalities. User interaction is required to exploit this vulnerability.
Here’s the summarized information in the requested format:
Platform: Android (uses Apache ExternalStorageProvider)
Version: Unaffected versions not specified (potential for widespread impact)
Vulnerability: File Path Filter Bypass
Severity: Critical
Date: November 2024 (based on CVE assignment date)
What Undercode Says:
This vulnerability (CVE-2024-43093) is critical because it allows attackers to potentially gain elevated privileges on an Android device. While user interaction is needed, the attacker could potentially trick the user into performing the necessary actions.
Here are some additional thoughts and potential mitigations:
Update Android devices to the latest security patches as soon as they become available. These patches likely address this vulnerability.
Be cautious when interacting with untrusted applications or websites, as they could be used to exploit this vulnerability.
If you are a developer using Apache ExternalStorageProvider, ensure proper unicode normalization is implemented to prevent such bypasses.
