CVE-2023-49780Network attack vector

Browser script execution through management-page XSS

Published Feb 12, 2025 · Updated Feb 18, 2025

Cross-site scripting in Extra Innovation Inc. acmailer CGI 4.0.5 and earlier allows remote attackers to execute scripts in a user's browser. Public advisories do not identify the affected parameter or explain how attacker-controlled input reaches executable browser context in the management page. Exploitation requires a user to access the affected management page; the published record describes no effect beyond arbitrary script execution in that browser.
