Security Bulletin: Tivoli Federated Identity Manager One Time Password Enforcement (CVE-2013-5429)

Security Bulletin


Under certain conditions, it may be possible to reuse IBM Tivoli Federated Identity Manager (TFIM) provided One Time Password tokens.

Vulnerability Details

CVE ID: CVE-2013-5429

The Tivoli Federated Identity Manager 6.2.2 Risk Based Access feature can be configured to require that a user provide a One Time Password (OTP) token before being able to perform a sensitive transaction. As the name implies, these tokens should only be valid for a single use. If a malicious user or system were to obtain such a token and attempt to use it to authenticate after it had already been used, such replay should be denied by TFIM. A vulnerability has been discovered that allows OTP tokens to be reused under special conditions.

The attack does not require local network access, but it does require authentication and highly specialized knowledge and techniques. An exploit would not impact the confidentiality of information or the availability of the system, but the integrity of data could be compromised.
