CVE-2019-13321

This vulnerability allows network adjacent attackers to execute arbitrary code on affected installations of Xiaomi Browser Prior to 10.4.0. User interaction is required to exploit this vulnerability in that the target must connect to a malicious access point. The specific flaw exists within the handling of HTTP responses to the Captive Portal. A crafted HTML response can cause the Captive Portal to to open a browser to a specified location without user interaction. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process. Was ZDI-CAN-7467.
