CVE-2015-0138 describes a vulnerability in GSKit, used by IBM Tivoli Directory Server and IBM Security Directory Server, where improper TLS state transition restrictions allow remote attackers to conduct cipher-downgrade attacks. Specifically, this flaw enables attackers to force the use of weaker EXPORT_RSA ciphers, similar to the "FREAK" issue. The vulnerability has a CVSS score of 4.3 (Medium), indicating a network-based attack with medium complexity, requiring no authentication, and potentially leading to partial integrity compromise. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
