A new attack vector named ArtiPACKED exploits GitHub Actions artifacts, potentially compromising repositories and cloud environments. Palo Alto Networks Unit 42 researchers revealed how misconfigurations and security flaws could lead to the leakage of tokens, opening opportunities for malicious actors to compromise services and push rogue code to production. Vulnerable open-source repositories have been found, prompting the need for organizations to reevaluate their use of GitHub artifacts.
Based on the meeting notes, the main takeaways are:
– A new attack vector in GitHub Actions artifacts called ArtiPACKED has been discovered, potentially leading to compromises in cloud environments and repositories.
– Artifacts in GitHub can leak sensitive tokens, such as GitHub tokens and third-party cloud service tokens, making them available to anyone with read access to the repository.
– The leaked tokens could grant unauthorized access to repositories and enable malicious actors to alter source code and push it to production through CI/CD workflows.
– Open-source projects are particularly at risk as artifacts are publicly available, making them an attractive target for extracting secrets.
– Vulnerabilities in the artifacts feature, including the exposure of an undocumented environment variable called ACTIONS_RUNTIME_TOKEN, could lead to remote code execution and token theft.
– The attack scenario involves exploiting race condition scenarios to steal and use tokens, with certain open-source repositories related to major cloud services found susceptible to the attack.
– GitHub has categorized the issue as informational, putting the onus on users to secure their uploaded artifacts and prompting organizations using Artifacts V3 to reevaluate their usage.
