CVE-2017-12868 WRITEUP CRITICAL WRITEUP
SimpleSAMLphp <1.14.13 - Session Fixation
The secureCompare method in lib/SimpleSAML/Utils/Crypto.php in SimpleSAMLphp 1.14.13 and earlier, when used with PHP before 5.6, allows attackers to conduct session fixation attacks or possibly bypass authentication by leveraging missing character conversions before an XOR operation.
CVSS 9.8
CVE-2017-12871 WRITEUP MEDIUM WRITEUP
SimpleSAMLphp 1.14.0-1.14.11 - Inadequate Encryption Strength via IV Reuse
The aesEncrypt method in lib/SimpleSAML/Utils/Crypto.php in SimpleSAMLphp 1.14.x through 1.14.11 makes it easier for context-dependent attackers to bypass the encryption protection mechanism by leveraging use of the first 16 bytes of the secret key as the initialization vector (IV).
CVSS 5.9
CVE-2018-7711 WRITEUP HIGH WRITEUP
SimpleSAMLphp < 1.15.4 - Improper Verification of Cryptographic Signature via Boolean Interpretation of Error Code
HTTPRedirect.php in the saml2 library in SimpleSAMLphp before 1.15.4 has an incorrect check of return values in the signature validation utilities, allowing an attacker to get invalid signatures accepted as valid by forcing an error during validation. This occurs because of a dependency on PHP functionality that interprets a -1 error code as a true boolean value.
CVSS 8.1
