Summary
A vulnerability in IOBit Advanced System Care 15 and Action Download Center allows low-privileged users to replace a genuine component with a malicious executable in the ProgramData folder, which has "rwx" permissions for all users. By using SetOpLock and waiting for CreateProcess, an attacker can achieve code execution with administrator privileges.
Risk Assessment
The organization is at risk of privilege escalation from a low-privileged user to full administrator, potentially leading to system compromise, malware installation, or data theft.
Recommendation
It is recommended to immediately update IOBit Advanced System Care to the latest version and restrict permissions on the ProgramData folder for unprivileged users by applying appropriate security policies.
