HIGH7.5EPSS 0.18%Name confusion in x509 Subject Alternative Name fields
發布日:2024/6/28修改日:2024/6/28
描述
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.
