VTech Admits Lack of Database Security Opened Door to Hack
A SQL injection, a common software flaw, was found to be the root cause in the VTech breach.VTech Holdings is now admitting to at least one of the root causes behind the breach that exposed information on millions of children and parents. In an update to the Frequently Asked Questions (FAQ) about the breach on Dec. 1, VTech now admits that its database security was lacking. "Regretfully our Learning Lodge, Kid Connect and PlanetVTech databases were not as secure as they should have been," VTech stated. "Upon discovering the breach, we immediately conducted a comprehensive check of the affected site and have taken thorough actions against future attacks. All other VTech online systems have not been affected." The database weakness is related to a class of security vulnerability known as SQL injection. SQL injection is not a new class of vulnerability as it was first publicly discussed back in 1998 by security researcher Jeff Forristal. In a 2013 video interview, Forristal said he wasn't surprised that SQL injection is still a common vulnerability that is widely exploited. "It is not surprising that this [VTech] breach would occur through SQL injection as this is among the most common and threatening Web flaws," Craig Young, cyber-security researcher at Tripwire, told eWEEK.
Young explained that SQL injection is one of the most prevalent Web security flaws, in which the attacker is able to alter the meaning of commands relayed to a database server. This is possible when data from a Web request is directly used to construct the database (SQL) query without replacing unsafe characters. He noted that sophisticated tools exist to automate the process of finding and exploiting SQL injection flaws, including a tool known as SQLmap, which enables even unskilled attackers to gain extensive access into a system.
