The remote code execution via man-in-the-middle attack vulnerabilities that we found in Baidu Browser’s auto-update mechanisms are consistent with vulnerabilities common in other third party software. In previous work, we have analyzed the auto-update mechanisms in popular third party software. The security issues in UC Browser were identified in documents leaked by Edward Snowden that indicated the Five Eyes intelligence alliance, consisting of intelligence agencies from Canada, the United States, the United Kingdom, Australia and New Zealand, had used these vulnerabilities as a means of identifying users.

That report documented UC Browser’s unencrypted transmission of sensitive user information, including IMSI, IMEI, Android ID, Wi-Fi MAC Address, geolocation data and user search queries. Our previous research includes a report on similar concerns with UC Browser, a popular mobile web browser owned by China-based e-commerce giant Alibaba. This report is a continuation of our prior work examining the security and privacy of popular mobile applications in Asia.

In addition, neither version of the application secures its software update process with a digital signature, which means that a malicious in-path actor could cause the browser to download and execute arbitrary code.

Such user data is transmitted, in both the Windows and Android versions, unencrypted or with easily decryptable encryption, which means that any in-path actor could acquire this data by collecting the traffic and performing any necessary decryption. The report identifies security concerns in both the Windows and Android versions of the browser that may expose personal user data, including a user’s geolocation, hardware identifiers, nearby wireless networks, web browsing data and search terms. This report provides a detailed analysis of how Baidu Browser manages and transmits user data during its operation. The browser offers a number of features beyond those found in standard browsers, including video and audio download tools and built-in torrent support.

The Windows version of Baidu Browser also transmits a number of personally identifiable data points, including a user’s search terms, hard drive serial number model and network MAC address, URL and title of all webpages visited, and CPU model number, without encryption or with easily decryptable encryption.

The Android version of Baidu Browser transmits personally identifiable data, including a user’s GPS coordinates, search terms, and URLs visited, without encryption, and transmits the user’s IMEI and a list of nearby wireless networks with easily decryptable encryption.

Baidu Browser, a web browser for the Windows and Android platforms, transmits personal user data to Baidu servers without encryption and with easily decryptable encryption, and is vulnerable to arbitrary code execution during software updates via man-in-the-middle attacks.
