Detailsinfo

A vulnerability, which was classified as very critical, was found in MobSF Mobile-Security-Framework-MobSF up to 4.0.6. This affects an unknown code block of the component a Extension File Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-23. The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Mobile Security Framework (MobSF) is a pen-testing, malware analysis and security assessment framework capable of performing static and dynamic analysis. Before 4.0.7, there is a flaw in the Static Libraries analysis section. Specifically, during the extraction of .a extension files, the measure intended to prevent Zip Slip attacks is improperly implemented. Since the implemented measure can be bypassed, the vulnerability allows an attacker to extract files to any desired location within the server running MobSF. This vulnerability is fixed in 4.0.7.
