Kerentanan Improper Verification of Cryptographic Signature pada omniauth saml, onelogin ruby-saml +1 lainnya. Skor CVSS 3.1 9.8 (Critical) menurut NVD.

Deskripsi (NVD)

ruby-saml provides security assertion markup language (SAML) single sign-on (SSO) for Ruby. An authentication bypass vulnerability was found in ruby-saml prior to versions 1.12.4 and 1.18.0 due to a parser differential. ReXML and Nokogiri parse XML differently, the parsers can generate entirely different document structures from the same XML input. That allows an attacker to be able to execute a Signature Wrapping attack. This issue may lead to authentication bypass. Versions 1.12.4 and 1.18.0 contain a patch for the issue.
