Bypassing airport security via SQL injection

Ian Carroll published a write-up together with Sam Curry on how they were able to add arbitrary crew members to bypass security screening or ride in a jump seat in the cockpit of an aircraft. They used SQL Injection (that seems to use MD5 password hashes!) on FlyCASS, a software system small airlines use to manage authorisation for their crew members at airports.

What was more shocking to me was seeing TSA allegedly trying to cover up the error.

The TSA press office said in a statement that this vulnerability could not be used to access a KCM checkpoint because the TSA initiates a vetting process before issuing a KCM barcode to a new member. However, a KCM barcode is not required to use KCM checkpoints, as the TSO can enter an airline employee ID manually. After we informed the TSA of this, they deleted the section of their website that mentions manually entering an employee ID, and did not respond to our correction. We have confirmed that the interface used by TSOs still allows manual input of employee IDs.
