Execution Of Arbitrary Authentication Source

SimpleSAMLphp is vulnerable to execution of arbitrary authentication source. This can happen because it does not validate the user input for choice of authentication source against a list of valid sources set by the administrator in multiauth module...

Denial Of Service (DoS)

simplesamlphp/saml2 is vulnerable to denial of service DoS attacks and spoofed SAML responses. It mishandles the conversion of return values to boolean which allows attackers to perform these attacks...

Security Bypass Via Signature Spoofing

simplesamlphp is vulnerable to security bypass via signature spoofing attacks. The attacks are possible because the SimpleSAMLXMLValidator incorrectly checks the return values in the signature validation, thereby allowing an attacker to spoof an invalid signature as valid. This flaw can also lead...
