Password disclosure via hardcoded six-octet MAC salt
Published Sep 12, 2024 · Updated Mar 25, 2025
Cryptographic weakness in Keyfactor EJBCA before 8.3.1 allows attackers to recover CMP authentication passwords from captured messages. The standalone CMP CLI client hardcodes a six-octet salt for password-based MAC instead of generating a random salt of at least eight octets, weakening resistance to dictionary attacks. Exposure requires production use of that client with password-based authentication, a dictionary-based password, a non-secure connection, and the ability to capture CMP messages in transit.
