RSA AM Prime Self-Service Portal could allow a malicious authenticated user (attacker) to replace his/her token serial number in a PIN change request with the token serial number of a victim user, which may change the PIN of the victim user to the PIN value specified by the attacker in the PIN change request. This may also deny victim?s access to the system. Versions 3.0 and 3.1 prior to build version 1915 are affected.
