scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick charac

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.".
