GHSA-293q-567p-wmwq
Spring Security Vulnerable to Unauthorized User Impersonation when Using X.509 Client Certificates
Quick fix
GHSA-293q-567p-wmwq — org.springframework.security:spring-security-web: upgrade to the fixed version with the command below.
# pom.xml: bump <version>6.5.11</version> for org.springframework.security:spring-security-webDetails
In Spring Security Web, `SubjectDnX509PrincipalExtractor` does not correctly handle certain malformed X.509 certificate CN values, which can lead to reading the wrong value for the username. In a carefully crafted certificate, this can lead to an attacker impersonating another user.
`SubjectDnX509PrincipalExtractor` is deprecated by this CVE and replaced with `SubjectX500PrincipalExtractor`. As part of updating, you should also migrate to `SubjectX500PrincipalExtractor`.
