Detailsinfo

A vulnerability was found in abrignoni ALEAPP up to 3.4.0. It has been rated as critical. This issue affects an unknown part of the file NQ_Vault.py. The manipulation of the argument file_name_from with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

ALEAPP (Android Logs Events And Protobuf Parser) through 3.4.0 contains a path traversal vulnerability in the NQ_Vault.py artifact parser that uses attacker-controlled file_name_from values from a database directly as the output filename, allowing arbitrary file writes outside the report output directory. An attacker can embed a path traversal payload such as ../../../outside_written.bin in the database to write files to arbitrary locations, potentially achieving code execution by overwriting executable files or configuration.

The weakness was released with Mobasi Security Team. It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2026-40027 since 04/08/2026. The exploitation is known to be easy. Attacking locally is a requirement. Technical details of the vulnerability are known, but there is no available exploit. The attack technique deployed by this issue is T1006 according to MITRE ATT&CK.

Applying the patch 0cafd8fe0027663420eb3d0fa821b2d1a713880d is able to eliminate this problem. The bugfix is ready for download at github.com.
