CVE-2024-43399: Opensecurity Mobile Security Framework

Critical severity, CVSS 9.8. EPSS: 1% chance of exploitation in the next 30 days.

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.
