CVE-2023-3557Network attack vector

Script execution via crafted preview parameters

Published Jul 8, 2023 · Updated Oct 28, 2024

Cross-site scripting in GZ Scripts Property Listing Script 1.0 allows remote attackers to execute script through a crafted preview request. Public sources identify preview.php and the page, layout, and sort_by parameters but do not disclose how the handler fails to neutralize them. Exploitation requires a victim to open the crafted request, and published assessments disagree on whether attacker authentication is required.
