CVE-2025-57197
📋 TL;DR
An improper access control vulnerability in Payeer Android app 2.5.0 allows local attackers with root access to bypass PIN verification and change the authentication PIN without knowing the current PIN. This affects Payeer Android app users on rooted devices. The vulnerability enables unauthorized PIN modification through dynamic instrumentation of the app.

⚠️ Risk & Real-World Impact
Worst Case
An attacker with physical access to a rooted device could change the PIN, lock out the legitimate user, and gain unauthorized access to the Payeer account and funds.
Likely Case
Malicious apps or users with root privileges on compromised devices could change PINs to hijack Payeer accounts for fraudulent transactions.
If Mitigated
With proper device security (no root access, verified boot), the attack surface is significantly reduced as root access is required.
🎯 Exploit Status
Exploitation requires root access to the device and ability to dynamically instrument the app (e.g., using Frida, Xposed). The technical details are documented in public references but no ready-to-use exploit code is published.

🔍 How to Verify
Check if Vulnerable:
Check if Payeer app version is 2.5.0 on a rooted Android device. The vulnerability exists in this specific version.Check Version:
adb shell dumpsys package com.payeer.android | grep versionNameVerify Fix Applied:
Update to latest Payeer version from Google Play Store and verify version is greater than 2.5.0. Test PIN change functionality requires current PIN.📡 Detection & Monitoring
Log Indicators:
- Unexpected PIN change events without prior successful authentication
- Multiple failed PIN attempts followed by successful PIN change
- App process instrumentation logs (if available)
Network Indicators:
- PIN change API calls without preceding authentication API calls
