CVE-2014-7425 in Doodle Devil Free
Summary
by MITRE
The Doodle Devil Free (aka com.joybits.doodledevil_free) application 2.1.4 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-2014-7425 affects the Doodle Devil Free Android application version 2.1.4, representing a critical security flaw in the application's secure communication implementation. This weakness stems from the application's failure to properly validate SSL/TLS certificates during network communications, creating a significant attack surface that adversaries can exploit to compromise user data integrity and confidentiality. The vulnerability specifically targets the certificate verification process, which is fundamental to establishing trust in secure communications between mobile applications and remote servers.
The technical flaw manifests as a missing certificate validation mechanism within the application's SSL implementation, allowing attackers to perform man-in-the-middle attacks by presenting fraudulent X.509 certificates to unsuspecting users. This type of vulnerability falls under CWE-295, which specifically addresses improper certificate validation, and represents a direct violation of secure communication protocols that are essential for protecting sensitive data transmission. The application's failure to implement proper certificate pinning or validation creates an environment where attackers can intercept and manipulate encrypted communications without detection, as the application accepts any certificate presented by a server regardless of its authenticity or trustworthiness.
From an operational perspective, this vulnerability exposes users to significant risks including data theft, session hijacking, and unauthorized access to personal information. Attackers can exploit this weakness to intercept sensitive communications, potentially gaining access to user credentials, personal data, or financial information transmitted through the application. The impact extends beyond individual user privacy concerns to potential corporate data breaches if the application handles business-related information or integrates with enterprise systems. The vulnerability's exploitation requires minimal technical skill, making it particularly dangerous as it can be leveraged by threat actors with varying levels of expertise.
The mitigation strategies for this vulnerability involve implementing proper SSL certificate validation mechanisms, including certificate pinning, certificate chain validation, and robust certificate trust verification processes. Organizations should implement certificate validation that checks certificate signatures, expiration dates, and trust relationships with recognized Certificate Authorities. The application should also incorporate secure communication libraries that enforce proper certificate validation standards and should be updated to use modern secure communication protocols. Additionally, implementing network monitoring and detection systems can help identify potential exploitation attempts. This vulnerability aligns with ATT&CK technique T1573.002, which covers the use of secure communication protocols for data exfiltration, and highlights the importance of proper certificate validation as a foundational security control that must be implemented in all mobile applications handling sensitive data. The remediation process should include comprehensive code review, security testing, and implementation of industry-standard secure coding practices to prevent similar vulnerabilities in future application releases.
