Summary
Leantime allows Stored Cross-Site Scripting (XSS)
Details

Summary

Stored XSS, also known as persistent XSS, is the more damaging of the two. It occurs when a malicious script is injected directly into a vulnerable web application.

Details

A Stored Cross-Site Scripting (XSS) vulnerability was found that could potentially compromise user data and pose a significant security risk to the platform.

PoC

  • Create a project
  • Navigate to project
  • Visit to the integration
  • Add malicious payload inside the webhook and save it.
  • Notice the alert dialogue indicating successful execution of the XSS payload.

Impact

This XSS vulnerability allows an attacker to execute malicious scripts in the context of a victim's browser when they click on a specially crafted link. This could lead to various malicious activities, including session hijacking, stealing sensitive information such as cookies or login credentials, and potentially compromising the entire platform's security.
