CVE-2025-7771
HIGH EXPLOITED RANSOMWAREThrottleStop.sys - Privilege Escalation
Title source: llmExploitation Summary
CVE-2025-7771 has been observed exploited in the wild (reported by VulnCheck KEV), including in ransomware campaigns. EIP tracks 15 public exploits from researchers including Xavi Beltran, DeathShotXD, Yuri08loveElaina.
AI-analyzed exploit summary This exploit leverages a kernel out-of-bounds write vulnerability in the Throttlestop driver to achieve privilege escalation by disabling protections on the LSASS process and injecting a malicious DLL. It demonstrates full exploit chain functionality, including driver installation, memory manipulation, and process protection bypass.
Description
ThrottleStop.sys, a legitimate driver, exposes two IOCTL interfaces that allow arbitrary read and write access to physical memory via the MmMapIoSpace function. This insecure implementation can be exploited by a malicious user-mode application to patch the running Windows kernel and invoke arbitrary kernel functions with ring-0 privileges. The vulnerability enables local attackers to execute arbitrary code in kernel context, resulting in privilege escalation and potential follow-on attacks, such as disabling security software or bypassing kernel-level protections. ThrottleStop.sys version 3.0.0.0 and possibly others are affected. Apply updates per vendor instructions.
