The SourceCodester Android application "Corona Virus Tracker App India" 1.0 uses MD5 for digest authentication in `OkHttpClientWrapper.java`. The `handleDigest()` function employs `MessageDigest.getInstance("MD5")` to hash credentials. MD5 is a broken cryptographic algorithm known to allow hash collisions. This makes the authentication mechanism vulnerable to replay, spoofing, or brute-force attacks, potentially leading to unauthorized access. The vulnerability corresponds to CWE-327 and aligns with OWASP M5: Insufficient Cryptography and MASVS MSTG-CRYPTO-4.
