Elad, Senior Security Researcher at Cycode, shares research on a supply chain vulnerability in Bazel affecting projects like Kubernetes and Google. The podcast discusses AI in cyber attacks, workflow vulnerabilities, composite actions, GitHub attack scenarios, and sponsor emphasis for risk mitigation.
Vulnerability in Bazel potentially impacts major projects like Kubernetes, Uber, and Google.
Collaborative vulnerability disclosure process leads to prompt mitigation strategies by Google.
Deep dives
Supply Chain Vulnerability in Basel Uncovered by SciCode
SciCode researchers identified vulnerabilities in workflows, particularly command injection vulnerabilities, which allow malicious inputs to interrupt and inject workflows. These vulnerabilities can be challenging to detect using standard security tools, as they reside in composite actions. Composite actions, akin to functions within workflows, proved to be susceptible to command injections, posing a significant risk.
Mitigation Measures and Response from Google
To mitigate vulnerabilities, it is advised to declare user inputs as environment variables before passing them into build pipelines in GitHub workflows. Google responded promptly to the disclosed vulnerability by implementing measures like declaring environment variables and minimizing workflow permissions to prevent potential attacks.
Collaborative Efforts and Disclosure Process
The collaborative effort between SciCode researchers and Google exemplified a smooth and effective vulnerability disclosure process. By detailing their findings and recommendations, SciCode facilitated a quick response from Google, leading to the implementation of mitigation strategies to enhance security in GitHub workflows.
Elad, a Senior Security Researcher from Cycode is sharing their research on "Cycode Discovers a Supply Chain Vulnerability in Bazel." This security flaw could let hackers inject harmful code, potentially affecting millions of projects and users, including Kubernetes, Angular, Uber, LinkedIn, Databricks, DropBox, Nvidia, Google, and many more.
The research states "We reported the vulnerability to Google via its Vulnerability Reward Program, where they acknowledged our discovery and proceeded to address and fix the vulnerable components."
