Log disclosure via hardcoded key and MD5 derivation
Published Jun 14, 2024 · Updated Feb 13, 2025
Hardcoded credentials in Toshiba Tec e-STUDIO MFPs allow local users to decrypt protected debug logs obtained from the device. The CreateDebugLog.sh script passes a shared literal password to OpenSSL AES-256 encryption and uses MD5 for one key-derivation path. Exploitation requires access to encrypted log files or the appliance filesystem and exposes log contents without altering device data.
