Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in the web interface in Airties RT-210 allow remote attackers to inject arbitrary web script or HTML via the (1) ddns_domainame or (2) ddns_account parameter to ddns.stm.

The CVE-2015-4679 vulnerability represents a critical cross-site scripting flaw discovered in the web interface of Airties RT-210 wireless routers. This vulnerability resides within the dynamic domain name system configuration handling mechanism, specifically targeting the ddns.stm management endpoint. The flaw enables remote attackers to execute malicious web scripts or HTML code within the context of authenticated users' browsers, potentially compromising the entire network infrastructure through session hijacking or data exfiltration attacks.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the router's web management interface. Attackers can exploit this weakness by manipulating the ddns_domainame or ddns_account parameters through the ddns.stm endpoint, which fails to properly escape or filter user-supplied data before rendering it in web responses. This primitive form of injection allows malicious payloads to be executed in the victim's browser context, bypassing standard security mechanisms that protect against unauthorized script execution. The vulnerability specifically affects the router's dynamic DNS configuration interface where users enter domain name and account information for remote access capabilities.
The operational impact of this vulnerability extends beyond simple script injection, as it provides attackers with persistent access to the router's administrative interface. Once exploited, attackers can modify router configurations, redirect traffic through malicious DNS servers, or establish persistent backdoors for future access. The vulnerability is particularly concerning because it affects the router's core management functionality, potentially allowing attackers to gain complete control over the network's internet access and configuration settings. This creates a significant risk for both residential and enterprise environments where these devices are commonly deployed.
Security professionals should implement immediate mitigations including network segmentation to isolate affected devices from critical systems, disabling unnecessary remote access features, and implementing web application firewalls to filter malicious requests. The vulnerability aligns with CWE-79 which describes cross-site scripting flaws in web applications, and corresponds to attack patterns within the MITRE ATT&CK framework under the T1071.004 technique for application layer protocol tunneling. Organizations should also consider updating firmware to versions that properly sanitize input parameters and implement proper output encoding for all user-supplied data within web interfaces. The affected Airties RT-210 devices require immediate firmware updates from the vendor to address this persistent vulnerability that could lead to complete network compromise.
