discovered a pair of problems with this update process, starting with the use of HTTP for fetching updates. Netgear’s CircleĪ handful of Netgear routers ship with the Circle Parental Control Service, and while the actual web filtering is off by default, the update service runs automatically anyway.
The workaround, that really does avoid detection? NSClassFromString(.joined(separator: "a")) The rest of the post is not security related, but raises some valid points about other failings of the App Store. Apple’s analysis will catch NSClassFromString() as accessing an Apple-only API. If you expected cutting-edge, advance techniques, prepare to be disappointed.

The followup post would be interesting on its own, showing some techniques for sneaking malicious code through the App Store’s analysis process. After six months sitting on the oldest issue, gave Apple a 10 day final deadline, and when that passed, published them all. Those are: a permission bypass allowing an app to read wifi information, an unintended method for an app to determine what other apps are installed, and a serious flaw allowing an app access to all sorts of things including a user’s authentication token. Two additional vulns were reported in May, and the third in March of this year. Three further security releases have come and gone, and still no disclosure or credit. asked, and was told that he would be credited in a later release. This data leak was fixed quietly, with no disclosure or credit from Apple. Prior to the fix, any app on the device could read the analytics logs unrestricted, a trove of information. But first, a vulnerability that was fixed, in release 14.7. iOS Woesĭenis Tokarev, AKA, has had it with Apple’s bug bounty program, and disclosed a trio of unfixed iOS bugs, far after 90 days had expired. I’ve said it before: Use LibreOffice, OpenOffice is known to be unsafe. The truth of the matter is that when the two projects forked, the programmers who really understood the codebase went to LibreOffice, and OpenOffice has had a severe programmer shortage ever since. LibreOffice fixed this in routine code maintenance back in 2014. And what about LibreOffice, the fork of OpenOffice? Surely it is also vulnerable? Nope.

The vulnerability report was sent way back on May 4th, over 90 days before full disclosure.

There is a release candidate that does contain the fix, but every stable install of OpenOffice in the world is currently vulnerable to this RCE. Normally we’d wrap by telling you to go get the update, but OpenOffice doesn’t have a stable release with this fix in it. The disclosure didn’t include a full PoC, but will likely be reverse engineered shortly. Turning this into an actual RCE exploit took a bit of doing, but is possible. A buffer is allocated based on the specified data type, but data is copied into this buffer with a different length, also specified in the dbase file. He knew exactly what he was looking for, and found vulnerable code right away. He managed to achieve code execution in dbfview, but that wasn’t enough.Īrmed with a vulnerability in one application, turned his attention to OpenOffice. He put together a fuzzing approach using Peach Fuzzer, and found a handful of possible vulnerabilities in the file format, by testing a very simple file viewer that supported the format. This database format was eventually used all over the place, and is still supported in Microsoft Office, Libreoffice, and OpenOffice. decided to concentrate on a file format, and picked the venerable dbase format. We start this week with a good write-up by on getting started on vulnerability hunting, and news of a problem in OpenOffice’s handling of DBase files.
