An internal product security audit discovered a session handling vulnerability in the web interface of ThinkAgile CP-SB (Storage Block) BMC in firmware versions prior to 1908.M. This vulnerability allows session IDs to be reused, which could provide unauthorized access to the BMC under certain circumstances. This vulnerability does not affect ThinkSystem XCC, System x IMM2, or other BMCs.
Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Cp_storage_block_firmware | Lenovo | * | 1908.m (excluding) |
Such a scenario is commonly observed when:
In the generic exploit of session fixation vulnerabilities, an attacker creates a new session on a web application and records the associated session identifier. The attacker then causes the victim to associate, and possibly authenticate, against the server using that session identifier, giving the attacker access to the user’s account through the active session.
