This security bulletin contains one medium risk vulnerability.
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to improper input validation in applications that use an LDAP CertStore from Bouncy Castle to validate X.509 certificates. During the certificate validation process, Bouncy Castle inserts the certificate's Subject Name into an LDAP search filter without any escaping, which leads to an LDAP injection vulnerability. A remote non-authenticated attacker can use a specially crafted X.509 certificate to bypass authentication process and gain unauthorized access to the application.Mitigation
