Dedicated to advancing the understanding and detection of software vulnerabilities—and explaining the latest vulnerability research from the GitHub Security Lab. Go behind the scenes with the GitHub Security Lab, a collaborative initiative that brings together security researchers, developers, and organizations to find and fix security vulnerabilities in open source software.
Object Graph Notation Language (OGNL) is a popular, Java-based, expression language used in popular frameworks and applications, such as Apache Struts and Atlassian Confluence. Learn more about bypassing certain OGNL injection protection mechanisms including those used by Struts and Atlassian Confluence, as well as different approaches to analyzing this form of protection so you can harden similar systems.
We’re excited to share the newest addition to our GitHub Bug Bounty Program!
It turns out that the first “all Google” phone includes a non-Google bug. Learn about the details of CVE-2022-38181, a vulnerability in the Arm Mali GPU. Join me on my journey through reporting the vulnerability to the Android security team, and the exploit that used this vulnerability to gain arbitrary kernel code execution and root on a Pixel 6 from an Android app.
Learn about the design behind, and solutions to, several of GitHub’s CTF challenge for Ekoparty’s 2022 event!
A glimpse into the backgrounds and day-to-day work of several GitHub employees in cybersecurity roles.
As we wrap up Cybersecurity Awareness Month, the GitHub bug bounty team is excited to spotlight one of the security researchers who participates in the GitHub Security Bug Bounty Program.
The GitHub Security Lab provided office hours for open source projects looking to improve their security posture and reduce the risk of breach. Here’s what we learned and how you can also participate.
In this post I’ll exploit CVE-2022-20186, a vulnerability in the Arm Mali GPU kernel driver and use it to gain arbitrary kernel memory access from an untrusted app on a Pixel 6. This then allows me to gain root and disable SELinux. This vulnerability highlights the strong primitives that an attacker may gain by exploiting errors in the memory management code of GPU drivers.
In this post I’ll exploit CVE-2022-1134, a type confusion in Chrome that I reported in March 2022, which allows remote code execution (RCE) in the renderer sandbox of Chrome by a single visit to a malicious site. I’ll also look at some past vulnerabilities of this type and some implementation details of inline cache in V8, the JavaScript engine of Chrome.
In this post I’ll exploit CVE-2022-22057, a use-after-free in the Qualcomm gpu kernel driver, to gain root and disable SELinux from the untrusted app sandbox on a Samsung Z flip 3. I’ll look at various mitigations that are implemented on modern Android devices and how they affect the exploit.
It was another record year for our Security Bug Bounty program. We’re excited to highlight some achievements we’ve made together with the bounty community from 2021!
Do you worry that a CVE will hurt the reputation of your project? In reality, CVEs are a tracking number, and nothing more. Here’s how we think of them at GitHub.
