Permissions, Privileges, and Access Controls
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.
CWE-264 - Permissions Privileges and Access Controls
CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
