“Clearly, this is a serious vulnerability. It is also somewhat difficult to diagnose, given the knowledge of the SSH protocol and a considerable .NET reverse-engineering effort required.” reads the published by WatchTowr. “However, the presence of the Illegal characters in path exception should grab the attention of any other researchers who are searching for the vulnerability, and the relative simplicity of exploitation lends itself to ‘accidental’ discovery.”
Researchers at Shadowserver Foundation also reported observing for CVE-2024-5806 and urge customers to address it.
