Severity ?
7.1 (High) - CVSS:3.0/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H
Summary
A flaw was found with the libssh API function ssh_scp_new() in versions before 0.9.3 and before 0.8.8. When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of the function, it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target.
