A weakness has been identified in atlaszz AI Photo Team Galleryit App 1.3.8.2 on Android. This affects an unknown part of the component gallery.photogallery.pictures.vault.album. This manipulation causes path traversal. The attack needs to be launched locally. The exploit has been made available to the public and could be exploited. The vendor was contacted early about this disclosure but did not respond in any way.
A critical path traversal vulnerability exists in the atlaszz AI Photo Team Galleryit App 1.3.8.2 for Android, allowing local attackers to potentially access and manipulate sensitive files. This vulnerability, publicly known and unpatched, could lead to data exfiltration, unauthorized file modification, and complete system compromise if exploited. The vendor has failed to address the issue, increasing the risk of widespread exploitation.
Step 1: Payload Preparation: The attacker crafts a malicious file path containing path traversal sequences (e.g., ../../) designed to target a specific file or directory outside the intended application scope.
Step 2: Input Injection: The attacker, operating locally on the Android device, injects the crafted malicious file path into a vulnerable input field within the Galleryit app. The specific input field is unknown, but likely related to file operations within the gallery.photogallery.pictures.vault.album component.
Step 3: Path Resolution: The application, due to the lack of input validation, processes the malicious file path. The path traversal sequences are not properly filtered or sanitized.
Step 4: File Access/Manipulation: The application attempts to access or manipulate the file specified by the resolved path. This could involve reading, writing, deleting, or executing the file, depending on the attacker's objective and the application's permissions.
The vulnerability stems from a lack of proper input validation and sanitization within the gallery.photogallery.pictures.vault.album component of the Galleryit app. Specifically, the application likely fails to adequately validate user-supplied input used to construct file paths. This allows an attacker to inject malicious path traversal sequences (e.g., ../../) into the input, enabling them to navigate outside the intended directory and access arbitrary files on the device. The root cause is a missing or inadequate implementation of secure file path handling, which should include input validation, sanitization, and potentially the use of a secure file path library or function. The absence of these security measures allows for the exploitation of the vulnerability, leading to unauthorized access and modification of files.
