Summary
Tata Motors iRA 2.0 through 26.7.3 and Tata Motors iRA.ev through 26.7.2 mobile applications are affected. The applications improperly implement SSL certificate pinning in their network security configuration, so certificate pinning is ineffective (CWE-295). An attacker positioned to intercept network traffic can intercept or modify communications between the application and its backend services, and user interaction is required.
