In the case of Shockwave, there are some mitigations missing in a number of modules, such as SafeSEH. “One of the things that helps make a vulnerability more difficult is how many of the exploit mitigations a vendor opts in to. “So not only are the vulnerabilities there, but they’re easier to exploit as well,” Dormann said. That’s because Shockwave has several modules that don’t opt in to trivial exploit mitigation techniques built into Microsoft Windows, such as SafeSEH. “So architecturally, it’s just flawed to provide its own Flash.”ĭormann said he initially alerted the public to this gaping security hole in 2012 via this advisory, but that he first told Adobe about this lackluster update process back in 2010.Īs if that weren’t bad enough, Dormann said it may actually be easier for attackers to exploit Flash vulnerabilities via Shockwave than it is to exploit them directly against the standalone Flash plugin itself. “Flash updates can come frequently, but Shockwave not so much,” Dormann said.
Worse yet, Dormann said, the current version of Shockwave for both Windows and Mac systems lacks any of the Flash security fixes released since January 2013. By my count, Adobe has issued nearly 20 separate security updates for Flash since then, including fixes for several dangerous zero-day vulnerabilities. In a recent post on the release of the latest bundle of security updates for Adobe’s Flash player, Dormann commented that Shockwave actually provides its own version of the Flash runtime, and that the latest Shockwave version released by Adobe has none of the recent Flash fixes. My re-education on this topic comes courtesy of Will Dormann, a computer security expert who writes threat advisories for Carnegie Mellon University’s CERT. But I was positively shocked this week to learn that this software introduces a far more pernicious problem: Turns out, it bundles a component of Adobe Flash that is more than 15 months behind on security updates, and which can be used to backdoor virtually any computer running it.
This author has long advised computer users who have Adobe‘s Shockwave Player installed to junk the product, mainly on the basis that few sites actually require the browser plugin, and because it’s yet another plugin that requires constant updating.
