CVE-2012-10032Public exploitNetwork attack vector

Privileged script execution via history-fragment injection

Published Aug 5, 2025 · Updated Jul 28, 2026

Cross-context scripting in Maxthon 3 3.1.7 build 600 through 3.2.2 build 1000 allows remote attackers to run privileged JavaScript. The about:history page treats a crafted URL-fragment payload as trusted content, so an injected event handler loads attacker-controlled script into the browser's trusted zone. A user must visit a malicious webpage; exposed Maxthon DOM APIs permit configuration changes, while affected 3.1 builds can write and launch an executable.
