In phpseclib before 1.0.22, 2.x before 2.0.46, and 3.x before 3.0.33, some characters in Subject Alternative Name fields in TLS certificates are incorrectly allowed to have a special meaning in regular expressions (such as a + wildcard), leading to name confusion in X.509 certificate host verification.
Weakness
Product A handles inputs or steps differently than Product B, which causes A to perform incorrect actions based on its perception of B’s state.
