The SimpleSAML_Auth_TimeLimitedToken class in SimpleSAMLphp 1.14.14 and earlier allows attackers with access to a secret token to extend its validity period by manipulating the prepended time offset.
According to WASC, “Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization.”
