Jailbreak artists exploit unpatched Apple iPhone, iPad bugs
But also provide patch to fix flaws, which Apple will probably do soon, says expert
Computerworld - Developers today said they used a pair of unpatched vulnerabilities in Apple's iOS to "jailbreak" the iPhone and iPad, including the first-ever hack of the iPad 2.
Some security experts immediately said the unfixed flaw -- and the fact it's essentially been released into the wild for miscreants to exploit -- posed a danger to iPhone and iPad owners.
"If they exploited the same vulnerability in a copy-cat maneuver, cybercriminals could create booby-trapped webpages that could -- if visited by an unsuspecting iPhone, iPod Touch or iPad owner -- run code on visiting devices," warned Graham Cluley, a senior technology consultant with U.K.-based Sophos, in a blog post.
To jailbreak an iOS device, users must visit the JailbreakMe website with an iPhone, iPad or iPod Touch running the current version of iOS, then install JailbreakMe 3.0.
The hack was released by a team led by someone identified only as "comex," and is the latest in a string of exploits that have circumvented Apple's App Store-only model, including one issued by the same group last August, just weeks after Apple rolled out iOS 4.
Ten days after JailbreakMe 2.0's 2010 debut, Apple patched the two vulnerabilities used by comex.
Charlie Miller, the only person to win prizes four years running at the Pwn2Own hacking contest, and a principal research consultant for Denver-based Accuvant, said it was likely Apple would react quickly to the newest jailbreak.
"This one is a remote code executable vulnerability," said Miller of one of the two bugs exploited by JailbreakMe 3.0. "Apple will probably patch this in a couple of weeks at the most."
Like Cluley, Miller was concerned by the bugs and exploits. "They're certainly a threat, and would be easy to make malicious," he said.
Miller also noted that because comex released a patch for the vulnerabilities at the same time as JailbreakMe 3.0, the situation wasn't serious. "For anyone worried about security, they can jailbreak their iPhone and then apply the patch," Miller said.
Comex published the fix, dubbed "PDF Patcher 2," on the Cydia app store, a popular site for downloading applications that run only on jailbroken iOS devices.
"Due to the nature of iOS, this patch can only be installed on a jailbroken device," said comex in a short FAQ on JailbreakMe. "Until Apple releases an update, jailbreaking will ironically be the best way to remain secure."
