CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2025-27773 – SimpleSAMLphp SAML2 library has incorrect signature verification for HTTP-Redirect binding
https://notcve.org/view.php?id=CVE-2025-27773
11 Mar 2025 — The SimpleSAMLphp SAML2 library is a PHP library for SAML2 related functionality. Prior to versions 4.17.0 and 5.0.0-alpha.20, there is a signature confusion attack in the HTTPRedirect binding. An attacker with any signed SAMLResponse via the HTTP-Redirect binding can cause the application to accept an unsigned message. Versions 4.17.0 and 5.0.0-alpha.20 contain a fix for the issue. • https://github.com/simplesamlphp/saml2/blob/9545abd0d9d48388f2fa00469c5c1e0294f0303e/src/SAML2/HTTPRedirect.php#L104-L113 • CWE-347: Improper Verification of Cryptographic Signature •

02 Dec 2024 — SimpleSAMLphp SAML2 library is a PHP library for SAML2 related functionality. When loading an (untrusted) XML document, for example the SAMLResponse, it's possible to induce an XXE. This vulnerability is fixed in 4.6.14 and 5.0.0-alpha.18. La librería SAML2 SimpleSAMLphp es una librería PHP para funciones relacionadas con SAML2. Al cargar un documento XML (no confiable), por ejemplo, SAMLResponse, es posible inducir un XXE. • https://github.com/simplesamlphp/saml2/commit/5fd4ce4596656fb0c1278f15b8305825412e89f7 • CWE-611: Improper Restriction of XML External Entity Reference •

https://notcve.org/view.php?id=CVE-2023-49087
30 Nov 2023 — xml-security is a library that implements XML signatures and encryption. Validation of an XML signature requires verification that the hash value of the related XML-document matches a specific DigestValue-value, but also that the cryptographic signature on the SignedInfo-tree (the one that contains the DigestValue) verifies and matches a trusted public key. If an attacker somehow (i.e. by exploiting a bug in PHP's canonicalization function) manages to manipulate the canonicalized version's DigestValue, it w... • https://github.com/simplesamlphp/xml-security/commit/f509e3083dd7870cce5880c804b5122317287581 • CWE-345: Insufficient Verification of Data Authenticity •

05 Mar 2018 — HTTPRedirect.php in the saml2 library in SimpleSAMLphp before 1.15.4 has an incorrect check of return values in the signature validation utilities, allowing an attacker to get invalid signatures accepted as valid by forcing an error during validation. This occurs because of a dependency on PHP functionality that interprets a -1 error code as a true boolean value.
