Security Advisories 🚨

🚨 Ruby SAML allows a SAML authentication bypass due to namespace handling (parser differential)

Summary

An authentication bypass vulnerability was found in ruby-saml 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.

Impact

This issue may lead to authentication bypass.

🚨 Ruby SAML allows a SAML authentication bypass due to DOCTYPE handling (parser differential)

Summary

An authentication bypass vulnerability was found in ruby-saml 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.

Impact

This issue may lead to authentication bypass.

🚨 Ruby SAML allows remote Denial of Service (DoS) with compressed SAML responses

Summary

ruby-saml is susceptible to remote Denial of Service (DoS) with compressed SAML responses.

Ruby-saml uses zlib to decompress SAML responses in case they're compressed. It is possible to bypass the message size check with a compressed assertion since the message size is checked before inflation and not after.

Impact

This issue may lead to remote Denial of Service (DoS).
