CVE-2017-5999

7.5 highEPSS 1.1%

High (7.5) in syspass syspass. EPSS 1.1% chance of exploitation in the next 30 days.

An issue was discovered in sysPass 2.x before 2.1, in which an algorithm was never sufficiently reviewed by cryptographers. The fact that inc/SP/Core/Crypt.class is using the MCRYPT_RIJNDAEL_256() function (the 256-bit block version of Rijndael, not AES) instead of MCRYPT_RIJNDAEL_128 (real AES) could help an attacker to create unknown havoc in the remote system.
