Summary
The vulnerability in Sophos SafeGuard products allows an attacker to escalate privileges locally by exploiting a flaw in the input handling of IOCTL 0x802022E0. By crafting a specific input buffer, attackers can manipulate the execution flow to modify the SEP_TOKEN_PRIVILEGES structure of the Token object within the exploit process. This can grant SE_DEBUG_NAME privileges, enabling the attacker to interface with higher-privileged SYSTEM processes and execute arbitrary code within their security context, potentially compromising system integrity.
