Technical details

A blind, time-based SQL injection vulnerability exists in the SSO OAuth endpoint of Koollab LMS version 5.3.2. An unauthenticated remote attacker can send specially crafted requests to the endpoint and use a time-based SQL oracle to exfiltrate data from the backend database. Successful exploitation allows for the retrieval of personally identifiable information (PII), user credentials, and valid JSON Web Tokens (JWTs), which can be leveraged for full account takeover. The vendor has patched this vulnerability in their SaaS environment; no user action is required for cloud-hosted instances.
