Executive Summary

This vulnerability exists in AVTECH EagleEyes 2.0.0 where the application disables proper hostname verification during HTTPS communication by using ALLOW_ALL_HOSTNAME_VERIFIER. This means the app accepts TLS certificates even if the certificate's hostname does not match the requested server's hostname, allowing attackers on the same network to perform man-in-the-middle attacks by intercepting or modifying the app's communications.

Impact Analysis

The vulnerability can allow an attacker on the same network to intercept or modify sensitive data transmitted between the app and backend services by exploiting the disabled hostname verification. This can lead to exposure of confidential information, data tampering, or unauthorized access to communications. [1]

Detection Guidance

This vulnerability can be detected by analyzing the application behavior or code to check if it uses SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER, which disables hostname verification. A practical approach is to use dynamic analysis tools such as Frida with a hooking script (e.g., hook.js) to intercept and modify the SDK_API_26 flag to false, emulating an older Android version and confirming if the vulnerable GetHttpsResponse() method is invoked. There are no specific network commands provided, but monitoring for man-in-the-middle attack indicators on the network could help detect exploitation attempts. [1]

Mitigation Strategies

Immediate mitigation steps include removing the use of SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER in the application code and enforcing strict hostname verification for all HTTPS connections. This can be done by validating the server's Common Name (CN) or Subject Alternative Name (SAN) against the requested hostname using HttpsURLConnection.getDefaultHostnameVerifier() or an equivalent strict verifier. Additionally, any legacy fallback logic that disables hostname checks on older Android versions should be removed or replaced with secure implementations to ensure consistent TLS validation. [1]
