Medium
5.4/10

Summary

teler is a real-time intrusion detection and threat alert dashboard. teler versions 2.0.0-rc through 2.0.0-rc.3 and 2.0.0-dev are vulnerable to DOM-based cross-site scripting (XSS) in the teler dashboard. When teler requests messages from the event stream at the `/events` endpoint, the log data displayed on the dashboard is not sanitized. This only affects authenticated users and can only be exploited based on detected threats if the log contains a DOM scripting payload.

CWE-79 - Cross Site Scripting

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
