Signature wrapping vulnerability in Spring Security
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.springframework.security:spring-security-core | >= 5.2.0, < 5.2.4 | 5.2.4 |
| Maven | org.springframework.security:spring-security-core | >= 5.3.0, < 5.3.2 | 5.3.2 |
Details
As written in the advisory (Markdown source, shown as plain text).
Spring Security versions 5.2.x prior to 5.2.4 and 5.3.x prior to 5.3.2 contain a signature wrapping vulnerability during SAML response validation. When using the spring-security-saml2-service-provider component, a malicious user can carefully modify an otherwise valid SAML response and append an arbitrary assertion that Spring Security will accept as valid.
