Recently, a critical security vulnerability, CVE-2024-24722, was discovered within the 12d Synergy Server and File Replication Server components. This vulnerability, an unquoted service path issue, could potentially allow attackers to obtain elevated permissions by exploiting the service path executable of 12d Synergy Server or 12d Synergy File Replication Server. In this blog post, we will explore the vulnerability, its potential impact, and steps to protect against it.
Vulnerability Description
An unquoted service path vulnerability exists within the 12d Synergy Server and File Replication Server components. Upon successful exploitation, a malicious actor may attain elevated privileges through the executable service path of the 12d Synergy Server or 12d Synergy File Replication Server. The following versions of the software are affected:
Exploit Details
When a service installed on a Windows system contains unquoted spaces within its path, an attacker can potentially replace the intended service binary with a malicious one. This occurs because Windows will look for a valid executable within each of the directories defined by the unquoted path. As a result, if a given directory contains spaces and is writeable by an attacker, the attacker can insert a malicious executable, which would be executed with the permissions of the legitimate service.
For example, consider the following unquoted service path vulnerability in the 12d Synergy Server component:
C:\Program Files\12d Synergy Server\12dSService.exe
In this example, a malicious actor could replace 12dSService.exe with their own malicious executable at the following locations:
C:\Program Files\12d.exe
Upon successful exploitation, the attacker would effectively gain control over the service.
Mitigation Steps
The developers of 12d Synergy have released patches addressing the unquoted service path vulnerability in versions 4.3.10.192, 5.1.5.221, and 5.1.6.235. To protect your system, you should update to the latest available version of the 12d Synergy software, as outlined below:
Verify that the 12d Synergy service path is now properly encapsulated within quotes, as shown below
"C:\Program Files\12d Synergy Server\12dSService.exe"
Conclusion
CVE-2024-24722 is a serious security issue that requires immediate attention. As demonstrated in this blog post, an attacker can easily exploit the vulnerability to gain elevated privileges through the 12d Synergy Server or 12d Synergy File Replication Server components. Fortunately, patches have been made available by the developers, and organizations are strongly urged to apply them swiftly to safeguard their systems.
