CVE-2013-10022Network attack vector

Script execution via unencoded contact-form fields

Published Apr 5, 2023 · Updated Aug 6, 2024

Cross-site scripting in BestWebSoft Contact Form 3.51 allows attackers to inject script through submitted contact-form fields. The cntctfrm_display_form and cntctfrm_check_form functions copy six POST fields into response state without HTML encoding; the patch adds htmlspecialchars to each value. Published assessments disagree on account requirements; exploitation also requires a user to render the crafted response, where script runs in the site origin.
