CVE-2012-10032: Maxthon International Ltd MAXTHON3 Browser

High severity, CVSS 8.7. EPSS: 1.3% chance of exploitation in the next 30 days.

Maxthon3 version 3.2.2 build 1000 and prior are vulnerable to cross context scripting (XCS) via the about:history page. The browser’s trusted zone improperly handles injected script content, allowing attackers to execute arbitrary JavaScript in a privileged context. This flaw enables modification of browser configuration and execution of arbitrary code through Maxthon’s exposed DOM APIs, including maxthon.program.Program.launch() and maxthon.io.writeDataURL(). Exploitation requires user interaction, typically by visiting a malicious webpage that triggers the injection.

Affected products

• Maxthon International Ltd MAXTHON3 Browser: from 3.1.7 build 600, up to and including 3.2.2 build 1000
