Summary
The vulnerability in Sophos SafeGuard products allows an attacker to escalate privileges locally through specific I/O control codes (IOCTLs). These IOCTLs fail to validate pointers and buffer sizes appropriately, potentially leading to unauthorized access. An attacker can exploit this flaw by supplying a controlled pointer to a kernel address, enabling modification of the SEP_TOKEN_PRIVILEGES structure of the exploited process's token. This manipulation can grant elevated privileges, allowing interaction with higher-tier processes and execution of code within a privileged security context, thus compromising system integrity.
