OneUptime Synthetic Monitor Remote Code Execution Vulnerability Analysis
A critical RCE vulnerability in OneUptime's Synthetic Monitors allows low-privileged users to execute arbitrary commands on the server by leveraging exposed Playwright browser objects.
CVE References
Affected
The vulnerability arises from untrusted Synthetic Monitor code executing in Node.js' vm module with access to Playwright's browser and page objects. This exposure allows malicious users to execute arbitrary commands on the server, leading to potential system compromise.
The proof-of-concept demonstrates that an attacker can inject code into monitor tests, using Playwright APIs to spawn executables. It highlights the critical need for isolating untrusted code from system-critical resources.
Monitor for unusual process spawns or file accesses originating from the application context. Implement log analysis to detect atypical Playwright API usage patterns indicative of exploitation attempts.
['Remove exposure of browser and page objects to untrusted code.', 'Isolate execution environments for user-provided code.', 'Sanitize and validate inputs in monitor tests to prevent malicious code injection.']
High likelihood of exploitation due to the severity of RCE. Potential for significant impact, including data breaches or service disruption, making it a high priority for remediation.
