VAR-201108-0124
Vulnerability from variot - Updated: 2023-12-18 13:25The LTPA STS module support implementation in IBM Tivoli Federated Identity Manager (TFIM) 6.2.0 before 6.2.0.9 and Tivoli Federated Identity Manager Business Gateway (TFIMBG) 6.2.0 before 6.2.0.9 relies on a static instance of a Java Development Kit (JDK) class, which might allow attackers to bypass LTPA token signature verification by leveraging lack of thread safety. IBM LTPA STS is prone to a security vulnerability related to the way it handles threads. The impact of this issue is currently unknown at the moment; however typical scenario may result in a denial-of-service condition or arbitrary data being overwritten. The following products are affected: IBM Tivoli Federated Identity Manager (TFIM) 6.2.0 prior to 6.2.0.9 IBM Tivoli Federated Identity Manager Business Gateway (TFIMBG) 6.2.0 prior to 6.2.0.9. The product provides web and federated single sign-on (SSO) capabilities to users across multiple applications. Attackers can exploit the lack of thread safety to bypass the signature verification of LTPA tokens
