The rsyncd service of the CGM CLININET is vulnerable to Authentication Bypass via IP spoofing. Access is granted based solely on the client's source IP address. An attacker able to spoof an allowed IP address, can bypass this check and gain the ability to edit files on the affected system. 

The vulnerability was confirmed to affect versions up to 2026.MS3 but later versions may also be vulnerable.
