[GLSA-200602-11] OpenSSH, Dropbear: Insecure use of system() call Vulnerability Scan
Vulnerability Scan Summary
OpenSSH, Dropbear: Insecure use of system() call
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200602-11
(OpenSSH, Dropbear: Insecure use of system() call)
To copy from a local filesystem to another local filesystem, scp
constructs a command line using 'cp' which is then executed via
system(). Josh Bressers discovered that special characters are not
escaped by scp, but are simply passed to the shell.
Impact
By tricking other users or applications to use scp on maliciously
crafted filenames, a local attacker user can execute arbitrary commands
with the rights of the user running scp.
Workaround
There is no known workaround at this time.
