The CVE-2013-3964 vulnerability represents a critical cross-site scripting flaw affecting Samsung mobile devices including the SHR-5162 and SHR-5082 models, with potential impact extending to other similar devices. This vulnerability resides in the web server implementation of these mobile devices, specifically within how they handle the PATH_INFO parameter in HTTP requests. The flaw enables remote attackers to execute malicious scripts against users who interact with compromised web applications running on these devices. The vulnerability stems from insufficient input validation and sanitization mechanisms that fail to properly filter or escape user-supplied data before processing it within the device's web interface.
The technical exploitation of this vulnerability occurs when an attacker crafts a malicious HTTP request containing specially formatted PATH_INFO data that includes executable script code. When the vulnerable Samsung device processes this request through its web server component, the malicious code becomes embedded within the device's response and gets executed in the context of the user's browser. This creates a persistent security risk where attackers can manipulate device functionality, steal user session information, or redirect users to malicious websites. The vulnerability is classified as a classic reflected XSS attack vector since the malicious payload is reflected back to the user through the device's web interface without being stored on the server.
From an operational impact perspective, this vulnerability compromises the security posture of affected Samsung mobile devices by allowing attackers to execute arbitrary code on devices that users trust. The attack surface is particularly concerning because these devices are often used in enterprise environments where they may have access to sensitive corporate data or systems. The vulnerability can be exploited through various attack vectors including phishing emails, malicious websites, or compromised applications that direct users to exploit the vulnerable PATH_INFO handling mechanism. Users who interact with malicious web content on these devices may unknowingly execute attacker-controlled scripts that can capture keystrokes, steal cookies, or perform unauthorized actions on behalf of the device user.
Security professionals should note that this vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications. The attack pattern corresponds to the ATT&CK technique T1212, which involves exploitation of web application vulnerabilities to execute malicious code in the context of a user's browser. Organizations should implement immediate mitigations including updating firmware to versions that address the PATH_INFO handling vulnerability, implementing web application firewalls to filter malicious requests, and conducting security awareness training to help users identify potential phishing attempts that may exploit this vulnerability. Network monitoring should be enhanced to detect suspicious PATH_INFO patterns that may indicate exploitation attempts. Additionally, device administrators should consider implementing access controls that limit web server functionality on mobile devices where possible, reducing the attack surface available to potential adversaries.
