- CWE-436
Description
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.
Affected configurations
• phpseclib phpseclib (>= 1.0.0 < 1.0.22)
• phpseclib phpseclib (>= 2.0.0 < 2.0.46)
• phpseclib phpseclib (>= 3.0.0 < 3.0.33)
