A significant security flaw has been identified in Xiaomi’s Interoperability Application, potentially compromising millions of devices worldwide. This vulnerability, designated as CVE-2024-45347, has been assigned a critical Common Vulnerability Scoring System (CVSS) score of 9.6, underscoring its severity and the urgent need for remediation.
Understanding the Vulnerability
The core issue resides in the application’s authentication mechanism. Specifically, a flaw in the verification logic allows malicious actors to bypass standard security protocols, granting them unauthorized access to affected devices. This means that attackers can potentially infiltrate devices without the need for user credentials or other standard authentication measures.
Technical Insights
The vulnerability is rooted in the application’s interoperability protocols, which are designed to facilitate seamless communication between Xiaomi devices and other smart home products. The flaw allows attackers to exploit weaknesses in these protocols, particularly during the authentication handshake process. By crafting malicious requests, attackers can circumvent normal security checks, leading to a complete system compromise. This could result in unauthorized access to sensitive data, installation of malicious software, or persistent control over the device.
Discovery and Reporting
The vulnerability was discovered by Liu Xiaofeng from the School of Cyberspace Security at Shandong University. Upon identifying the flaw, Liu promptly reported it to Xiaomi’s Security Center (MiSRC), enabling the company to take swift action in addressing the issue.
Affected Versions and Immediate Actions
The specific version affected by this vulnerability is Xiaomi’s Interconnection Application version 3.1.895.10. Users operating this version are at immediate risk and are strongly advised to update their software without delay. Xiaomi has released a patched version, 3.1.921.10, which rectifies the flaw and reinstates the application’s security integrity.
Potential Impact
The high CVSS score of 9.6 indicates that successful exploitation of this vulnerability could have severe consequences. Attackers could gain complete control over the affected device, leading to:
– Unauthorized access to personal and sensitive data.
– Installation of malicious software or malware.
– Persistent surveillance or control over device functionalities.
Given the application’s role in connecting Xiaomi devices with other smart home products, the potential for widespread impact is significant.
