Description

A Weak Cryptography for Passwords issue was discovered in General Electric (GE) Multilin SR 750 Feeder Protection Relay, firmware versions prior to Version 7.47; SR 760 Feeder Protection Relay, firmware versions prior to Version 7.47; SR 469 Motor Protection Relay, firmware versions prior to Version 5.23; SR 489 Generator Protection Relay, firmware versions prior to Version 4.06; SR 745 Transformer Protection Relay, firmware versions prior to Version 5.23; SR 369 Motor Protection Relay, all firmware versions; Multilin Universal Relay, firmware Version 6.0 and prior versions; and Multilin URplus (D90, C90, B95), all versions. Ciphertext versions of user passwords were created with a non-random initialization vector leaving them susceptible to dictionary attacks. Ciphertext of user passwords can be obtained from the front LCD panel of affected products and through issued Modbus commands.
