Simplesamlphp XML-security 1.6.11

Apache XML Security for C++ through 2.0.4 implements the XML Signature Syntax and Processing (XMLDsig) specification without protection against an SSRF payload in a KeyInfo element. NOTE: the project disputes this CVE Record on the grounds that any vulnerabilities are the result of a failure to configure XML Security for C++ securely. Even when avoiding this particular issue, any use of this library would need considerable additional code and a deep understanding of the standards and protocols involved to arrive at a secure implementation for any particular use case. We recommend against continued direct use of this library.

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 would be possible to forge the signature. This issue has been patched in version 1.6.12 and 5.0.0-alpha.13.
