Mojic: Observable Timing Discrepancy in HMAC Verification
MEDIUM 4.7EPSS 0.2%
Mojic is a CLI tool to transform readable C code into an unrecognizable chaotic stream of emojis. Prior to 2.1.4, the CipherEngine uses a standard equality operator (!==) to verify the HMAC-SHA256 integrity seal during the decryption phase. This creates an Observable Timing Discrepancy (CWE-208), allowing a potential attacker to bypass the file integrity check via a timing attack. This vulnerability is fixed in 2.1.4.
