Description Preview
A local privilege escalation vulnerability exists in Alfredo Milani Comparetti SpeedFan version 4.52. This security flaw allows local attackers to execute malicious code with elevated privileges by using specially constructed programs that exploit the vulnerability. The issue stems from improper access controls in the application, which can be leveraged to gain higher system privileges than intended, potentially leading to complete system compromise.
Overview
SpeedFan is a hardware monitoring program that can access temperature sensors, change fan speeds, and monitor voltages. The vulnerability in version 4.52 allows a local attacker to escalate privileges on the affected system. This is particularly concerning as SpeedFan runs with system-level privileges to access hardware components, but fails to properly restrict how these privileges can be accessed by other processes or users. An attacker with limited access to a system can exploit this vulnerability to gain administrative privileges, potentially leading to unauthorized access to sensitive information, installation of malware, or complete system compromise.
Remediation
To mitigate this vulnerability, users should:
- Update to a newer version of SpeedFan if one becomes available with security patches
- If no patch is available, consider uninstalling SpeedFan or restricting its use to only trusted environments
- Implement the principle of least privilege for all user accounts on systems where SpeedFan is installed
- Monitor system activities for suspicious behavior that might indicate exploitation attempts
- Consider using alternative hardware monitoring software that does not have known security vulnerabilities
