What is CVE-2023-49111?
CVE-2023-49111 is a medium-severity cross-site scripting vulnerability in Kiuwan SAST, published on 20 Jun 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
For Kiuwan installations with SSO (single sign-on) enabled, an unauthenticated reflected cross-site scripting attack can be performed on the login page "login.html". This is possible due to the request parameter "message" values being directly included in a JavaScript block in the response. This is especially critical in business environments using AD SSO authentication, e.g. via ADFS, where attackers could potentially steal AD passwords.
