CVE-2023-2862Public exploitNetwork attack vector

Cross-site scripting via unfiltered ajaxDivId reflection

Published May 24, 2023 · Updated Aug 2, 2024

Cross-site scripting in SiteServer CMS 7.2.0 through 7.2.1 allows attackers to execute browser script via a crafted ajaxDivId value. The Submit handler in ActionsSearchController fails to neutralize attacker-controlled ajaxDivId before returning it in web content. A victim must load the crafted response; successful exploitation runs attacker-supplied script in that user's SiteServer origin, while published assessments disagree on whether authentication is needed.
