Description
OneUptime is a solution for monitoring and managing online services. Prior to 10.0.21, an unauthenticated path traversal in the /workflow/docs/:componentName endpoint allows reading arbitrary files from the server filesystem. The componentName route parameter is concatenated directly into a file path passed to res.sendFile() in orker/FeatureSet/Workflow/Index.ts with no sanitization or authentication middleware. This vulnerability is fixed in 10.0.21.
Analysis
Unauthenticated path traversal in OneUptime versions before 10.0.21 allows remote attackers to read arbitrary files from the server via the /workflow/docs/:componentName endpoint, which fails to sanitize user input before passing it to file operations. Public exploit code exists for this vulnerability, affecting all users of vulnerable versions without authentication requirements. …

Remediation
Within 24 hours: Immediately assess OneUptime deployment versions and document all instances running versions prior to 10.0.21. Within 7 days: Implement WAF rules to block malicious requests to /workflow/docs/ endpoint with path traversal patterns (../, encoded variants); restrict network access to OneUptime administrative interfaces; isolate OneUptime servers from untrusted networks. …
