iPhone Vulnerability Yields Root Access Via SMS

snydeq writes "Pwn2Own winner Charlie Miller has revealed an SMS vulnerability that could provide hackers with root access to the iPhone. Malicious code sent by SMS to run on the phone could include commands to monitor location using GPS, turn on the phone's microphone to eavesdrop on conversations, or make the phone join a DDoS attack or botnet, Miller said. Miller did not provide detailed description of the SMS vulnerability, citing an agreement with Apple, which is working to fix the vulnerability in advance of Black Hat, where Miller plans to discuss the attack in greater detail. 'SMS is a great vector to attack the iPhone,' Miller said, as SMS can send binary code that the iPhone processes without user interaction. Sequences can be sent to the phone as multiple messages that are automatically reassembled, thereby surpassing individual SMS message limits of 140 bytes."

    So this is bad news for the iPhone but it seems like any carrier of the iPhone should want to implement a simple filter to remove any malicious SMSs from the system.

      It's not the carrier's responsibility to look at all SMS messages going through their system and filter them out, it's the iPhone's responsibility to not execute untrusted code in the first place. If this was a Microsoft device that's exactly what people would be saying.

    This might be linked to the MobileMe Find My iPhone, Remote Wipe, and remote message facilities. If these are commands sent by SMS message from MobileMe, then perhaps they can be overflowed to run arbitrary commands.

    After all, if you can wipe the phone remotely, then that system has root access, does it not?

    And the case of binary data, you're dead wrong.

    GSM SMS payload is 140 8-bit characters, or bytes, depending how you look at it.

    The default SMS text encoding format uses 7-bits, and employs a bit-shifting algorithm to pack 160 7-bit characters in to 140 bytes. Binary formats can't use this compression, as, well, they need all eight bits.

    I recently canceled texting completely on my iPhone 3GS. Texting fees are outrageous and I'm not putting up with them anymore. If you want to text me, send it to my email address. Your phone probably supports texting to an email address and you don't even realize it. You can also reply to free texts I send you and I get notified instantly.

    Sure, I can't receive texts sent to my phone number, but that's a sacrifice I'm willing to make if I'm going to help my country kick this ridiculous habit of overpaying for tiny emails.
