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.


Security Impact Summary

This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.0, indicating it requires adjacent network access with relatively low complexity though user interaction is required and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 1 product from mi organizations running these solutions should prioritize assessment and patching.

Historical Context

Reported in 2020, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For mi's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
