- ** DISPUTED ** scp in OpenSSH through 8.3p1 allows
command injection in the scp.c toremote function, as
demonstrated by backtick characters in the destination
argument. NOTE: the vendor reportedly has stated that
they intentionally omit validation of 'anomalous
argument transfers' because that could 'stand a great
chance of breaking existing workflows.'(CVE-2020-15778)
