CVE-2020-12062 at MITRE

Description

** DISPUTED ** The scp client in OpenSSH 8.2 incorrectly sends duplicate responses to the server upon a utimes system call failure, which allows a malicious unprivileged user on the remote server to overwrite arbitrary files in the client's download directory by creating a crafted subdirectory anywhere on the remote server. The victim must use the command scp -rp to download a file hierarchy containing, anywhere inside, this crafted subdirectory. NOTE: the vendor points out that "this attack can achieve no more than a hostile peer is already able to achieve within the scp protocol" and "utimes does not fail under normal circumstances."

Note from the SUSE Security Team

This issue has been disputed. The 'scp' protocol allows shell execution, it can not really be made secure against users doing more than filetransfer. Please consider using 'sftp' instead.
