CVE-2012-2646 in Sleipnir Mobile
Summary
by MITRE
The Sleipnir Mobile application before 2.1.0 and Sleipnir Mobile Black Edition application before 2.1.0 for Android do not properly implement the WebView class, which allows remote attackers to obtain sensitive information via a crafted application.

The CVE-2012-2646 vulnerability affects the Sleipnir Mobile and Sleipnir Mobile Black Edition applications for Android systems prior to version 2.1.0. This security flaw resides in the application's implementation of the WebView class, which serves as the core component for rendering web content within mobile applications. The vulnerability represents a critical weakness in the application's security architecture that directly impacts how sensitive information is handled and protected.
The technical flaw manifests through improper implementation of the WebView class, which creates a pathway for remote attackers to exploit the application's security boundaries. When applications utilize WebView components to display web content, they must properly configure security settings to prevent unauthorized access to local resources, cookies, and other sensitive data. In the case of Sleipnir Mobile, the WebView implementation failed to adequately restrict access to the application's internal storage and sensitive information, allowing attackers to craft malicious applications or web pages that could extract confidential data from the vulnerable application's context.
This vulnerability enables attackers to potentially access sensitive information through crafted application payloads that exploit the WebView's security misconfigurations. The impact extends beyond simple data exposure, as the flaw could allow for privilege escalation, session hijacking, or unauthorized access to user accounts and personal data. The remote nature of the attack means that adversaries can exploit this vulnerability without requiring physical access to the device or local network presence, making it particularly dangerous in mobile environments where applications frequently handle sensitive user information.
From a cybersecurity perspective, this vulnerability aligns with CWE-200, which addresses "Information Exposure," and represents a classic example of inadequate input validation and security configuration. The flaw demonstrates how mobile application developers must properly configure WebView components to prevent information disclosure attacks, particularly when applications interact with web-based content. The vulnerability also relates to ATT&CK technique T1059, which covers "Command and Scripting Interpreter," as attackers could potentially leverage this flaw to execute malicious code within the application's security context.
Organizations and users should immediately update to Sleipnir Mobile version 2.1.0 or later to address this vulnerability. The mitigation strategy involves proper WebView security configuration including disabling unnecessary features, implementing strict content security policies, and ensuring that sensitive data is properly isolated from web content rendering components. Security teams should also conduct thorough application security reviews to identify similar WebView implementation issues in other mobile applications and ensure that proper sandboxing and access control mechanisms are in place to prevent unauthorized information disclosure.
