The (1) Htpasswd authentication source in the authcrypt module and (2) SimpleSAML_Session class in SimpleSAMLphp 1.14.11 and earlier allow remote attackers to conduct timing side-channel attacks by leveraging use of the standard comparison operator to compare secret material agai...
-
CriticalCVSS 9.8 EPSS 1.7% PoC
SimpleSAMLphp 1.7.0 through 1.14.10 might allow attackers to obtain sensitive information, gain unauthorized access, or have unspecified other impacts by leveraging incorrect persistent NameID generation when an Identity Provider (IdP) is misconfigured.
-
HighCVSS 7.5 EPSS 1.3% PoC
The InfoCard module 1.0 for SimpleSAMLphp allows attackers to spoof XML messages by leveraging an incorrect check of return values in signature validation utilities.
-
HighCVSS 7.5 EPSS 2.4% PoC
The multiauth module in SimpleSAMLphp 1.14.13 and earlier allows remote attackers to bypass authentication context restrictions and use an authentication source defined in config/authsources.php via vectors related to improper validation of user input.
-

The validateSignature method in the SAML2\Utils class in SimpleSAMLphp before 1.14.10 and simplesamlphp/saml2 library before 1.9.1, 1.10.x before 1.10.3, and 2.x before 2.3.3 allows remote attackers to spoof SAML responses or possibly cause a denial of service (memory consumption...
-
MediumCVSS 6.3 EPSS 1.2% PoC
The SimpleSAML_XML_Validator class constructor in SimpleSAMLphp before 1.14.11 might allow remote attackers to spoof signatures on SAML 1 responses or possibly cause a denial of service (memory consumption) by leveraging improper conversion of return values to boolean.
-
MediumCVSS 5.3 EPSS 1.3% PoC
The sanitycheck module in SimpleSAMLphp before 1.14.1 allows remote attackers to learn the PHP version on the system via unspecified vectors.
