CVE-2020-5407 – Signature Wrapping Vulnerability with spring-security-saml2-service-provider

https://notcve.org/view.php?id=CVE-2020-5407

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. Spring Security versiones 5.2.x anteriores a 5.2.4 y versiones 5.3.x anteriores a 5.3.2, contienen una vulnerabilidad de empaquetado de firma durante la comprobación de respuesta SAML. Cuando se usa el componente spring-security-saml2-service-provider, un usuario malicioso puede modificar cuidadosamente una respuesta SAML válida y agregar una afirmación arbitraria que Spring Security aceptará como válida. • https://lists.apache.org/thread.html/r73af928cf64bebf78b7fa4bc56a5253273ec7829f5f5827f64c72fc7%40%3Cissues.servicemix.apache.org%3E https://lists.apache.org/thread.html/ra19a4e7236877fe12bfb52db07b27ad72d9e7a9f5e27bba7e928e18a%40%3Cdev.geode.apache.org%3E https://lists.apache.org/thread.html/rd99601fbca514f214f88f9e53fd5be3cfbff05b350c994b4ec2e184c%40%3Cdev.geode.apache.org%3E https://tanzu.vmware.com/security/cve-2020-5407 https://www.oracle.com/security-alerts/cpuApr2021.html https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle&# • CWE-347: Improper Verification of Cryptographic Signature •
