Technical details

Pgpool-II improperly handles NUL bytes (\0) in the Common Name (CN) field of X.509 certificates during client authentication, allowing domain name validation to be bypassed. An unauthenticated attacker can craft a malicious certificate to authenticate as another user without providing credentials. The vulnerability affects versions 4.0.x through 4.7.2 and requires network access but no prior authentication.
