CWE-287: Improper AuthenticationSecurity Assertion Markup Language (SAML) is an XML-based markup language for security assertions regarding authentication and permissions, most commonly used for single sign-on (SSO) services.Some XML DOM traversal and canonicalization APIs may be inconsistent in handling of comments within XML nodes. Incorrect use of these APIs by some SAML libraries results in incorrect parsing of the inner text of XML nodes such that any inner text after the comment is lost prior to cryptographically signing the SAML message. Text after the comment therefore has no impact on the signature on the SAML message.A remote attacker can modify SAML content for a SAML service provider without invalidating the cryptographic signature, which may allow malicious users to bypass primary authentication for the affected SAML service providerThe following CVEs are assigned:CVE-2017-11427 - OneLogin’s "python-saml"CVE-2017-11428 - OneLogin’s "ruby-saml"CVE-2017-11429 - Clever’s "saml2-js"CVE-2017-11430 - "OmniAuth-SAML"CVE-2018-0489 - Shibboleth openSAML C++CVE-2018-5387 - Wizkunde SAMLBaseMore information is available in the researcher's blog post.
