CVE-2017-18486

https://notcve.org/view.php?id=CVE-2017-18486

Jitbit Helpdesk before 9.0.3 allows remote attackers to escalate privileges because of mishandling of the User/AutoLogin userHash parameter. By inspecting the token value provided in a password reset link, a user can leverage a weak PRNG to recover the shared secret used by the server for remote authentication. The shared secret can be used to escalate privileges by forging new tokens for any user. These tokens can be used to automatically log in as the affected user. Jitbit Helpdesk en versiones anteriores a 9.0.3, permite a los atacantes remotos escalar privilegios debido al manejo inapropiado del parámetro userHash del archivo User/AutoLogin. • https://github.com/Kc57/JitBit_Helpdesk_Auth_Bypass https://packetstormsecurity.com/files/144334/JitBit-Helpdesk-9.0.2-Broken-Authentication.html https://www.exploit-db.com/exploits/42776 https://www.trustedsec.com/2017/09/full-disclosure-jitbit-helpdesk-authentication-bypass-0-day • CWE-332: Insufficient Entropy in PRNG •
