CVE-2017-7905 Detail

Modified

This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.

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.
