CrushFTP Discloses New Flaw

The development comes as CrushFTP has warned customers of an “unauthenticated HTTP(S) port access” vulnerability affecting CrushFTP versions 10 and 11. It has yet to be assigned a CVE identifier.

“This issue affects CrushFTP v10/v11 but does not work if you have the DMZ function of CrushFTP in place,” the company said. “The vulnerability was responsibly disclosed, it is not being used actively in the wild that we know of, no further details will be given at this time.”

According to details shared by cybersecurity company Rapid7, successful exploitation of the vulnerability could lead to unauthenticated access via an exposed HTTP(S) port.

With security flaws in VMware and CrushFTP previously exploited by malicious actors, it’s essential that users move quickly to apply the updates as soon as possible.
