Dräger Protector Software < 6.4.2 has a local privilege escalation flaw due to insecure file permissions, allowing code execution as NT SYSTEM.
Vulnerability
Dräger Protector Software prior to version 6.4.2 contains a local privilege escalation vulnerability. This is due to insecure file system permissions that allow local attackers to execute arbitrary code with elevated privileges. The vulnerability affects Protector Software versions earlier than 6.4.2 [2].
Exploitation
Local attackers can exploit this vulnerability by replacing binaries or loaded modules on the host system. This requires the attacker to have local access to the system and the ability to modify files with elevated privileges [2].
Impact
Successful exploitation allows attackers to execute arbitrary code with NT SYSTEM privileges. This means an attacker can gain complete control over the host system, including access to sensitive data and the ability to modify system configurations [2].
Mitigation
Dräger Protector Software version 6.4.2 and later contain fixes for this vulnerability. Users are advised to update to version 6.4.2 or later. Information regarding specific release dates for the patched version is not yet disclosed in the available references [2].
