The CVE-2016-1175 vulnerability represents a critical cross-site request forgery flaw discovered in the AQUOS Photo Player HN-PP150 device firmware versions ranging from 1.02.00.04 through 1.03.01.04. This vulnerability falls under the CWE-352 category, which specifically addresses Cross-Site Request Forgery weaknesses in software applications. The affected device operates as a network-connected media player that allows remote access to its web-based administrative interface, creating a potential attack surface where malicious actors can exploit the lack of proper authentication validation mechanisms. The vulnerability exists due to the absence of anti-CSRF tokens or other protective measures in the web interface, making it susceptible to unauthorized command execution through forged requests that appear to originate from legitimate authenticated users.
The technical implementation of this vulnerability stems from the device's web server implementation that fails to validate the origin of HTTP requests sent to its administrative endpoints. When a user authenticates to the device's web interface, the authentication session remains active without proper CSRF protection mechanisms. Attackers can craft malicious web pages or exploit existing web content that, when visited by an authenticated user, automatically submits requests to the vulnerable device's administrative interface. This allows remote attackers to perform actions such as changing administrative passwords, modifying device settings, or accessing restricted functionalities without possessing valid credentials. The flaw is particularly concerning because it operates at the application layer of the device's network stack, where it can be exploited through standard web-based attack vectors.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it enables attackers to completely compromise the device's administrative functions and potentially gain persistent control over the network-connected media player. An attacker who successfully exploits this vulnerability can manipulate the device's configuration, potentially redirecting it to malicious servers or disabling security features. This represents a significant risk for organizations that deploy these devices in corporate environments or public spaces, as the compromised device could serve as a foothold for broader network infiltration. The vulnerability's remote nature means that attackers do not require physical access to the device, making it particularly dangerous for IoT and embedded systems where physical security is often assumed to provide additional protection layers.
The security implications of CVE-2016-1175 align with ATT&CK technique T1566, which covers credential access through social engineering and web-based attacks. Organizations should implement immediate mitigations including firmware updates from the vendor, network segmentation to isolate affected devices, and monitoring for unusual administrative activities. The vulnerability demonstrates the critical importance of CSRF protection in embedded web interfaces and highlights how even seemingly benign networked devices can represent significant security risks when proper authentication validation is absent. Device administrators should also consider implementing additional security controls such as IP whitelisting for administrative access and regular security audits to identify similar vulnerabilities in other network-connected devices within their infrastructure.
