An authentication bypass vulnerability in ruby-saml prior to versions 1.12.4 and 1.18.0 allows an attacker to execute a Signature Wrapping attack due to parser differential.

Shortened by a language model. Every number, version and name in it is checked against the description below, and it is only shown when it is clearly shorter.

Description

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.
