In order to perform actions that requires higher privileges, the Quest KACE System Management Appliance 8.0.318 relies on a message queue managed that runs with root privileges and only allows a set of commands. One of the available commands allows changing any user's password (including root). A low-privilege user could abuse this feature by changing the password of the 'kace_support' account, which comes disabled by default but has full sudo privileges.

A famous example of this type of weakness being exploited is the eBay attack. eBay always displays the user id of the highest bidder. In the final minutes of the auction, one of the bidders could try to log in as the highest bidder three times. After three incorrect log in attempts, eBay password throttling would kick in and lock out the highest bidder's account for some time. An attacker could then make their own bid and their victim would not have a chance to place the counter bid because they would be locked out. Thus an attacker could win the auction.
