Horizon Alert
Summary of the vulnerability and why it matters
A security vulnerability has been identified in the automated build process for a documentation website, which could allow an attacker to disclose sensitive secrets used in the build environment. This issue arises from how untrusted code from external contributions is handled before deployment. The main concern is to confirm if our organization uses this specific documentation build process.
- Code handling flaws in documentation builds.
- Potential for secret disclosure during builds.
- Confirm relevance and exposure to this process.
Attack Path
How an attacker could exploit the issue
An attacker can compromise the documentation build process by submitting a malicious fork of the repository. When a pull request from this fork is processed, the build system checks out the untrusted code before installing dependencies. This allows the attacker's code, such as a specially crafted `setup.py` file, to execute with elevated privileges during the build, potentially leading to the disclosure of sensitive tokens.
- Entry condition: Submit a malicious fork.
- Trigger point: Processing a pull request from the fork.
- Resulting risk: Secret disclosure and system compromise.
Live Threat
Current exploitation, exposure, and threat context
A malicious actor could potentially gain access to sensitive information within the build system by submitting a specially crafted pull request from a forked repository. This could occur when the build process, specifically the `build-pr.yml` workflow, checks out code from an untrusted fork before installing dependencies. The compromise of secrets like API tokens and GitHub tokens could lead to further unauthorized actions within the repository's infrastructure.
- Repository secrets and tokens.
- Malicious code in a forked repository.
- Disclosure of secrets and system compromise.
Operational Fix
Recommended remediation, mitigation, and detection steps
This critical vulnerability resides within the Salty documentation repository's CI/CD pipeline. Responsibility for remediation likely falls to the platform or development team managing the repository and its associated build processes. The immediate first step is to identify all instances of this repository, assess the business criticality of the docs.saltbox.dev website, and confirm the ownership of the repository.
- Platform or development team owns the issue.
- Verify repository build process and configuration.
- Plan code merge and deployment to production.
