Official description

A vulnerability was identified in D-Link DGS-1100-08PD 1.00.006. This issue affects some unknown processing of the file /etc/boa.conf of the component Web Interface. Such manipulation leads to least privilege violation. The attack may be launched remotely. The attack requires a high level of complexity. The exploitability is assessed as difficult. The exploit is publicly available and might be used.

The underlying weakness: Incorrect Privilege Assignment

A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
