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...

Improper Verification of Cryptographic Signature

Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to differences in XML document DOCTYPE parsing between REXML and Nokogiri, implemented in xmlsecurity.rb. An attacker can bypass authentication via Signature Wrapping attack...

GHSA-92RQ-C8CF-PRRQ 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...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in decoderawsaml, which does not sufficiently check the size of a compressed SAML response. An attacker can cause the application to consume excessive resources by sending a large...
