A command injection vulnerability was found in Rsync. An attacker can use this vulnerability to execute arbitrary commands on a remote host via arguments passed to Rsync for a copy operation. The attacker needs to know the SSH login password to be able to exploit this issue.

@Pedro: there are not a lot of details, do you have any more insight what this is about by chance ?
Comment 2 Pedro Monreal Gonzalez 2021-09-01 09:14:12 UTC 
Thanks for opening the bug. There is not much information yet about it and nothing related in upstream Github. From the bug description, I can see that to reproduce it the attacker needs to know the ssh key!

I'll keep an eye upstream and in RH Bugzilla.
