Description

Detects improper SSL/TLS certificate validation in Android applications. This vulnerability occurs when an app fails to properly validate SSL certificates during secure communications, potentially allowing attackers to intercept sensitive data through man-in-the-middle attacks. Improper certificate validation severely compromises the security of network communications.

Detection Strategy

• Scans application code for custom TrustManager implementations that accept all certificates without validation

• Identifies WebView configurations that accept all SSL certificates without proper verification

• Detects override methods like checkServerTrusted() that are empty or return without proper certificate checks

• Finds instances where hostname verification is disabled or bypassed in network connections
