SITOS six Build v6.2.1 allows a user to change their password and recovery email address without requiring them to confirm the change with their old password. This would allow an attacker with access to the victim's account (e.g., via XSS or an unattended workstation) to change that password and address.

Demo Examples

Weak Password Recovery Mechanism for Forgotten Password

CWE-640

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.
