Recommended response

Check inventory. Check lockfiles and deployed manifests for curl/curl, curl/curl, curl/curl.
Review the reported fix. Update curl/curl to 8.14.2; curl/curl to b011e3fcfb06d6c0278595ee2ee297036fbe9793; Siemens/RUGGEDCOM RST2428P to V4.0 if you use the affected versions. Test the change in a non-production environment first.

Sources and claim methodology

Upstream source description

curl's code for managing SSH connections when SFTP was done using the wolfSSH powered backend was flawed and missed host verification mechanisms. This prevents curl from detecting MITM attackers and more.
