CVE-2022-26250: 
Synametrics SynaMan vulnerability analysis and mitigation

Synaman v5.1 and below contains a vulnerability related to weak file permissions (CVE-2022-26250) that allows authenticated attackers to escalate privileges. The vulnerability was discovered and reported in early 2022, affecting all versions of Synaman up to version 5.1 (Bencteux Post, NVD).

The vulnerability stems from weak folder permissions in the default installation directory 'C:\Synaman', which grants write permissions to any user for the contents of the directory and its sub-folders. Additionally, the program installs a service called 'SynaMan' that runs with LocalSystem privileges, allowing local users to escalate to 'NT AUTHORITY\SYSTEM' by replacing the service's binary with a malicious one (Bencteux Post).

The vulnerability allows authenticated attackers to escalate their privileges to NT AUTHORITY\SYSTEM level, effectively gaining complete control over the affected system. This enables attackers to execute arbitrary code with the highest system privileges (Bencteux Post).

The vulnerability is exploitable by any authenticated user who can access the system. The attack involves replacing the SynaMan.exe binary with a malicious payload, taking advantage of the weak file permissions. The exploitation process requires a system restart to take effect (Bencteux Post).

Version 5.1 partially addresses this vulnerability by changing the default installation directory to Program Files. However, it's noted that even version 5.1 may not completely fix the issue. Users should ensure they have the latest updates installed and consider implementing additional access controls (Bencteux Post).
