An anonymous reader sends a link to DarkReading on the recent announcement by Princeton researchers of four major Web sites on which they found exploitable cross-site request forgery vulnerabilities. The sites are the NYTimes, YouTube, Metafilter, and INGDirect. All but the NYTimes site have patched the hole. "...four major Websites susceptible to the silent-but-deadly cross-site request forgery attack — including one on INGDirect.com's site that would let an attacker transfer money out of a victim's bank account... Bill Zeller, a PhD candidate at Princeton, says the CSRF bug that he and fellow researcher Edward Felton found on INGDirect.com represents... 'the first example of a CSRF attack that allows money to be transferred out of a bank account that [we're] aware of.'... CSRF is little understood in the Web development community, and it is therefore a very common vulnerability on Websites. 'It's basically wherever you look,' says [a security researcher]." Here are Zeller's Freedom to Tinker post and the research paper (PDF).
