Researchers at Rapid7 have reported a “possible mass exploitation” of vulnerabilities in Progress Software’s WS_FTP Server. This is a program that enables the upload and download of files to and from a server.
Rapid7 reported that from 30th September, it has observed “multiple instances of WS_FTP exploitation in the wild”.
With secure file transfer technologies continuing to be popular targets for attackers, the advice is to update or upgrade to a patched version of WS_FTP Server such as 8.8.2.
Also, those using the Ad Hoc Transfer module in WS_FTP Server who can’t update to a fixed version, are advised to consider disabling or removing the module.
