Accellion Secure File Transfer Appliance before 8_0_105 does not properly restrict access to sensitive commands and arguments that run with extra sudo privileges, which allows local administrators to gain privileges via (1) arbitrary arguments in the --file_move action in /usr/local/bin/admin.pl, or a hard link attack in (2) chmod or (3) a certain cp command.
Accellion Kiteworks appliances before kw2016.03.00 use setuid-root permissions for /opt/bin/cli, which allows local users to gain privileges via unspecified vectors.
Accellion FTA 9_12_411 and earlier is affected by OS command execution via a local web service call. The fixed version is FTA_9_12_416 and later.
