One of China‘s most popular browsers, Maxthon, has a bug in its Windows version that can allow a hacker to take admin control and install malware. A report by security firm SafeBreach notes it reported the vulnerability in September.
The anomaly lets a hacker install a program into a service that is run by the “NT AUTHORITYSYSTEM,” – the admin account. When browser‘s service, a program essential to run the browser, MxService, running with admin privileges starts, it searches for a non-existent file called program.exe before it moves to other executables to fire up the actual browser app.
Using this bug, a hacker can place a dummy executable with that name, and the browser would think it’s harmless. The research team said the cause of the exploit is in the install package.
Through this vulnerability, an attacker can gain admin privileges, install malicious code, and bypass windows security to run apps that might not get execution permission otherwise.
SafeBreach said Maxthon for Windows version 5.1.0 to 5.2.7 are affected. Maxthon’s website claims its browser is used by more than 670 million people, but it hasn’t specified any number for its Windows users.
The browser hasn’t specified any date for a patch, so you should avoid using it at the moment.
