CVE-2014-7734 in Reds Anytime Bail
Summary
by MITRE
The Reds Anytime Bail (aka com.onesolutionapps.redsanytimebailandroid) application 1.1 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-2014-7734 affects the Reds Anytime Bail Android application version 1.1, representing a critical security flaw in the application's SSL/TLS certificate validation mechanism. This weakness stems from the application's failure to properly verify X.509 certificates presented by SSL servers during secure communications. The implementation violates fundamental security principles that govern secure network communications, creating an exploitable condition that undermines the integrity of the application's encrypted data transmission capabilities. The vulnerability specifically targets the certificate verification process, which is a cornerstone of the Transport Layer Security protocol and essential for maintaining secure client-server communications.
The technical flaw manifests as an insufficient certificate validation routine that allows the application to accept any SSL certificate without proper cryptographic verification. This includes certificates that may have been issued by untrusted Certificate Authorities, expired certificates, or certificates that do not match the expected hostname. The absence of certificate pinning or proper certificate chain validation creates multiple attack vectors for malicious actors. According to CWE-295, this vulnerability falls under the category of "Improper Certificate Validation" where the application fails to properly validate the authenticity and trustworthiness of SSL certificates. The flaw represents a direct violation of the TLS protocol's security guarantees and creates a pathway for attackers to establish fraudulent secure connections with the application.
The operational impact of this vulnerability extends beyond simple data interception, as it enables sophisticated man-in-the-middle attacks that can compromise sensitive user information. Attackers can exploit this weakness to impersonate legitimate servers and establish secure connections with the application, potentially gaining access to personal data, financial information, or other sensitive credentials. The vulnerability affects the confidentiality and integrity of data transmitted between the mobile application and its backend servers, making it particularly dangerous for applications handling user accounts, payment information, or personal identification details. This type of attack vector is commonly categorized under ATT&CK technique T1041, where adversaries use man-in-the-middle techniques to intercept and manipulate network traffic.
Mitigation strategies for this vulnerability should focus on implementing proper SSL certificate validation mechanisms within the application. The recommended approach includes implementing certificate pinning to ensure that the application only accepts certificates from specific trusted authorities or specific certificate fingerprints. Additionally, the application should implement proper certificate chain validation, verify certificate expiration dates, and ensure hostname matching between the certificate and the server being accessed. Security patches should enforce strict certificate validation routines that align with industry best practices and standards such as those outlined in the OWASP Mobile Security Project. Organizations should also consider implementing network monitoring solutions to detect potential exploitation attempts and establish proper security auditing procedures to identify similar vulnerabilities in other mobile applications. The remediation process should include thorough code review of all network communication components and implementation of automated testing procedures to validate certificate validation logic before deployment.
