CVE-2021-24387Network attack vector

Script execution via unsanitized search parameter

Published Jul 6, 2021 · Updated Aug 3, 2024

Cross-site scripting in Contempo Creative Inc. Real Estate 7 before 3.1.1 allows remote attackers to execute script via a crafted search request. The search listing page reflects the ct_community parameter without adequate sanitization, placing attacker-controlled markup into the response. Exploitation requires a victim to load the crafted URL, and the reflected script can affect that user's web session without directly changing server data.
