Detection Guidance

This vulnerability can be detected by checking the version of OneUptime installed on your system. Versions prior to 10.0.98 are vulnerable.

Since the exploit involves creating a malicious synthetic monitor using Playwright code that leverages prototype pollution for remote code execution, detection can involve monitoring for unusual or unauthorized synthetic monitors or Playwright scripts in the OneUptime dashboard.

No specific detection commands are provided in the available resources.

Executive Summary

This vulnerability affects OneUptime, an open-source monitoring and observability platform. Before version 10.0.98, OneUptime used the Node.js vm module as an isolation primitive. However, this module was not designed for secure isolation and can be escaped by exploiting error objects and infinite recursion.

Impact Analysis

The vulnerability has a very high severity with a CVSS base score of 9.9, indicating it can be exploited remotely with low complexity and no user interaction. It can lead to complete compromise of confidentiality, integrity, and availability, meaning an attacker could potentially execute arbitrary code, access sensitive data, or disrupt services.
