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.
This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.
