https://notcve.org/view.php?id=CVE-2018-6856
Sophos SafeGuard Enterprise before 8.00.5, SafeGuard Easy before 7.00.3, and SafeGuard LAN Crypt before 3.95.2 are vulnerable to Local Privilege Escalation via IOCTL 0x8020601C. By crafting an input buffer we can control the execution path to the point where a global variable will be written to a user controlled address. We can take advantage of this condition to zero-out the pointer to the security descriptor in the object header of a privileged process or modify the security descriptor itself and run code in the context of a process running as SYSTEM. Sophos SafeGuard Enterprise en versiones anteriores a la 8.00.5, SafeGuard Easy en versiones anteriores a la 7.00.3, y SafeGuard LAN Crypt en versiones anteriores a la 3.95.2 son vulnerables a una escalada de privilegios local mediante IOCTL 0x8020601C. Manipulando un búfer de entrada, es posible controlar la ruta de ejecución al puntero, en el que se escribirá una variable global en una dirección controlada por el usuario. • http://seclists.org/fulldisclosure/2018/Jul/20 https://community.sophos.com/kb/en-us/131934 https://labs.nettitude.com/blog/cve-2018-6851-to-cve-2018-6857-sophos-privilege-escalation-vulnerabilities • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Sophos SafeGuard Enterprise before 8.00.5, SafeGuard Easy before 7.00.3, and SafeGuard LAN Crypt before 3.95.2 are vulnerable to Local Privilege Escalation via IOCTL 0x80202298. By crafting an input buffer we can control the execution path to the point where the nt!memset function is called to zero out contents of a user-controlled address. We can take advantage of this condition to zero-out the pointer to the security descriptor in the object header of a privileged process or modify the security descriptor itself and run code in the context of a process running as SYSTEM.
