September 30, 2008, 9:51 AM — After shelving plans to detail a browser clickjacking vulnerability that is indirectly related to Adobe Systems' products at the company's request earlier this month, a security researcher plans to detail the flaw next month.
Jeremiah Grossman, chief technology at White Hat Security, will discuss the vulnerability at the Hack In The Box (HITB) conference in Kuala Lumpur, Malaysia. "We have no ETA on Adobe fixes, but we're hopeful that it'll be weeks and not months. Whether or not they 'patch,' it will not change the content of my keynote speech," he wrote in an e-mail.
Grossman was scheduled to detail the clickjacking flaw with Robert Hansen, CEO of SecTheory, at the Open Web Application Security Project conference in New York, but they pulled the presentation at Adobe's request. The hackers said no pressure was put on them, but Adobe wanted time to study and address the vulnerability before it was made public. "This is not an evil 'the man is trying to keep us hackers down' situation," Hansen wrote on his blog at the time.
Clickjacking is an attack where a user clicks on a button in a browser, thinking the button will perform a specific function, such submitting a news story to Digg, but instead an attacker hijacks the button to use it for another purpose. The vulnerability is "obviously scary enough for Adobe to call it a critical issue and ask for more time, even though they were only indirectly affected," Grossman wrote in an e-mail.
Over the weekend, Grossman and Hansen planned to inform Adobe of their intent to proceed with the presentation and make the proof-of-concept code they developed available.
"We gave Adobe time out of courtesy because they asked and we have a good working relationship with them. They are using the time productively, but we could not agree to another delay," Grossman wrote. "Our belief is clickjacking as an issue is not a problem in their software, but with browsers in general. It would not be fair to the others that it does impact to be without the information they need."
HITB will be held in Kuala Lumpur from Oct. 27-30.
