While every security update should be installed promptly, this one is a bit more urgent because the attack is “in the wild” already, meaning that hackers are already taking advantage of this vulnerability to breach security.ĭesignated CVE-2022-2294, this vulnerability was actually a flaw with the Chromium project, the open-source code that Google’s Chrome browser is built upon. Microsoft just released an Edge browser update that patches a dangerous flaw that could allow a cleverly designed attack to execute arbitrary code. Indeed it solved the problem, but it wasn't the best place to insert the code 😋.

l=238?q=ResolveSuggestedNameExtension&ss=chromium%2Fchromium%2Fsrc One of solution was to just replace character % in suggestedName to _. Here, I would like to underline that I am not a c++ dev 😎. I gave myself challange to repair the bug. Let a = await window.showSaveFilePicker(' or '$USER' return real username then target is vulnerable

Thanks for the thumbs up and subscriptions 😀 👍 👨‍💻 Code Proof of concept The simplest one The vulnerability is in the File system access API, more specifically in window.showSaveFilePicker() method. All of them were vulnerable, except for Brave. There are several web browsers based on the chromium engine, for instance, Google Chrome, Microsoft Edge, Opera, and Brave. A security bug was found in Chromium 92 version and patched in 97 version. Successful exploitation of this vulnerability can lead to the leak of user's secrets stored inside a system environment variables. 🤝 Show your support - give a ⭐️ if you liked the content | SHARE on TwitterĬVE-2022-0337 System environment variables leak on Google Chrome, Microsoft Edge and Opera 📝 Description
