Name of the Vulnerable Software and Affected Versions Sakai versions prior to 23.5 Sakai versions prior to 25.0

Description Sakai is a Collaboration and Learning Environment. The EncryptionUtilityServiceImpl component initialized an AES256TextEncryptor password (

serverSecretKey

) using RandomStringUtils with the default java.util.Random, which is a non-cryptographic pseudo-random number generator (PRNG). This PRNG can be predicted from limited state or seed information, reducing the effectiveness of the generated key. An attacker obtaining ciphertexts may be able to reconstruct the

serverSecretKey

and decrypt affected data.

Recommendations Update to Sakai version 23.5 or later. Update to Sakai version 25.0 or later.
