CVE-2014-7647 in BOOKING DISCOUNT
Summary
by MITRE
The BOOKING DISCOUNT (aka com.wmygoodhotelscom) application 0.1 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

The vulnerability identified as CVE-2014-7647 affects the BOOKING DISCOUNT Android application version 0.1, specifically targeting its implementation of secure communication protocols. This flaw represents a critical security weakness in the application's handling of encrypted network connections, where the software fails to properly validate SSL/TLS certificates presented by remote servers. The absence of certificate verification creates a significant attack surface that malicious actors can exploit to compromise the integrity of communications between the mobile client and backend services. This particular vulnerability falls under the broader category of insecure cryptographic implementation practices that have been consistently flagged by security standards and frameworks as dangerous flaws in mobile applications.
The technical implementation flaw manifests in the application's failure to perform proper certificate chain validation and trust verification processes that are fundamental to secure SSL/TLS communication. When the Android application establishes connections to remote servers, it should validate that certificates are issued by trusted certificate authorities, have not expired, and properly match the expected hostname. However, the BOOKING DISCOUNT application bypasses these essential verification steps, allowing any certificate to be accepted regardless of its authenticity or trustworthiness. This weakness directly violates established security protocols and represents a clear violation of the principles outlined in the OWASP Mobile Top 10 and industry best practices for secure mobile application development. The vulnerability is classified as a weakness in certificate validation procedures and aligns with CWE-295, which specifically addresses the failure to validate certificates.
The operational impact of this vulnerability extends beyond simple data interception, as it enables sophisticated man-in-the-middle attacks that can completely compromise user sessions and sensitive transaction data. Attackers can create malicious certificates that appear legitimate to the vulnerable application, allowing them to decrypt and modify communications between users and the booking service. This creates opportunities for credential theft, session hijacking, and financial fraud, particularly when users enter sensitive information such as credit card details, personal identification, or login credentials. The attack vector is particularly dangerous in public Wi-Fi environments where network traffic interception is more common, and the vulnerability affects any communication channel that relies on SSL/TLS encryption. The implications align with ATT&CK technique T1041, which describes the use of man-in-the-middle attacks to intercept and manipulate network communications.
Mitigation strategies for this vulnerability require immediate implementation of proper certificate verification mechanisms within the application's network communication layer. Developers must ensure that the application validates certificate chains against trusted root certificates, checks certificate expiration dates, and performs hostname verification to prevent certificate spoofing attacks. The recommended approach involves implementing certificate pinning techniques where specific certificate fingerprints or public keys are hardcoded within the application, preventing the acceptance of unauthorized certificates even if they appear valid. Additionally, the application should be updated to use modern SSL/TLS protocol versions and cipher suites that provide stronger cryptographic security. Organizations should also consider implementing network monitoring solutions to detect potential exploitation attempts and establish proper certificate management procedures that include regular security assessments of mobile applications. The fix should align with industry standards such as those defined in NIST SP 800-52 for certificate management and the Android security guidelines for secure network communication implementation.
