Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file). ## Affected - `openssh <= 7.9` - `winscp <= 5.1.3` - `ubuntu_linux = 14.04` - `ubuntu_linux = 16.04` - `ubuntu_linux = 18.04` - `ubuntu_linux = 18.10` - `debian_linux = 8.0` - `debian_linux = 9.0` - `enterprise_linux = 7.0` - `enterprise_linux = 8.0` - `enterprise_linux_eus = 8.1` - `enterprise_linux_eus = 8.2` - `enterprise_linux_eus = 8.4` - `enterprise_linux_eus = 8.6` - `enterprise_linux_server_aus = 8.2` - `enterprise_linux_server_aus = 8.4` - `enterprise_linux_server_aus = 8.6` - `enterprise_linux_server_tus = 8.2` - `enterprise_linux_server_tus = 8.4` - `enterprise_linux_server_tus = 8.6` - `fedora = 30` - `mina_sshd = 2.2.0` - `freebsd < 12.0` - `freebsd = 12.0` - `m10-1_firmware < xcp2361` - `m10-4_firmware < xcp2361` - `m10-4s_firmware < xcp2361` - `m12-1_firmware < xcp2361` - `m12-2_firmware < xcp2361` - `m12-2s_firmware < xcp2361` - `m10-1_firmware < xcp3070` - `m10-4_firmware < xcp3070` - `m10-4s_firmware < xcp3070` - `m12-1_firmware < xcp3070` - `m12-2_firmware < xcp3070` - `m12-2s_firmware < xcp3070` - `scalance_x204rna_firmware < 3.2.7` - `scalance_x204rna_eec_firmware < 3.2.7` ## Remediation Upgrade past the affected range: - `freebsd 12.0` - `m10-1_firmware xcp3070` - `m10-4_firmware xcp3070` - `m10-4s_firmware xcp3070` - `m12-1_firmware xcp3070` - `m12-2_firmware xcp3070` - `m12-2s_firmware xcp3070` - `scalance_x204rna_firmware 3.2.7` - `scalance_x204rna_eec_firmware 3.2.7`
