CVE-2024-33401Public exploit

Browser script execution via crafted mnum parameter

Published Apr 29, 2024 · Updated Mar 25, 2025

Cross-site scripting in DedeCMS 5.7.113 allows remote authenticated users to execute browser scripts through a crafted mnum parameter. The public record identifies mnum as the untrusted input but does not disclose the receiving handler, output context, or exact missing neutralization operation. A low-privilege session is required, and successful exploitation runs script in the application's browser origin without a reported service interruption.
