The vulnerability identified as CVE-2024-31973 affects Hitron CODA-4582 2AHKM-CODA4589 devices running firmware version 7.2.4.5.1b8, representing a critical stored cross-site scripting flaw that enables remote attackers within Wi-Fi proximity to execute malicious code. This vulnerability resides in the web interface of the device, specifically targeting the 'Network Name (SSID)' input fields located on the /index.html#wireless_basic page. The flaw allows an attacker to inject malicious JavaScript code that gets stored on the device and subsequently executed whenever the affected page is accessed by any user, including legitimate administrators or network users. The vulnerability's remote nature combined with the requirement for only Wi-Fi proximity makes it particularly concerning as attackers can exploit it without requiring physical access or complex network penetration techniques.
The technical implementation of this stored XSS vulnerability stems from inadequate input validation and output encoding within the web application's handling of SSID parameters. When users enter network names into the designated fields, the application fails to properly sanitize or escape special characters that could be interpreted as HTML or JavaScript code. This deficiency creates an environment where malicious payloads can be injected and persistently stored within the device's configuration interface. The attack vector leverages the device's web-based management interface, making it accessible through standard HTTP/HTTPS protocols, and the stored nature of the vulnerability means that the malicious code remains active until manually removed from the device's configuration. This vulnerability directly maps to CWE-79 which describes improper neutralization of input during web page generation, and aligns with ATT&CK technique T1566.001 for initial access through spearphishing attachments or links, though in this case the attack occurs through the device's own web interface.
The operational impact of this vulnerability extends beyond simple data theft or disruption as it provides attackers with persistent access to the device's management interface, potentially enabling them to modify network configurations, steal credentials, or establish backdoor access points. An attacker could inject malicious scripts that redirect users to phishing sites, harvest login credentials, or even deploy additional malware payloads that leverage the device's network connectivity. The vulnerability's location within wireless network configuration settings makes it particularly dangerous as it could allow attackers to create malicious SSIDs that appear legitimate to network users, facilitating man-in-the-middle attacks or unauthorized network access. Furthermore, since the device may be used in residential or commercial environments, the attack surface could include multiple users who might unknowingly interact with the maliciously modified SSID fields. The vulnerability could also be exploited to gain deeper insights into the device's internal network configuration, potentially leading to further exploitation of connected systems.
Mitigation strategies for CVE-2024-31973 should prioritize immediate firmware updates from Hitron to address the stored XSS vulnerability, as this represents the most effective solution to eliminate the root cause. Network administrators should also implement network segmentation and access controls to limit the potential impact of exploitation, particularly by restricting access to the device's management interface to trusted networks only. Additional defensive measures include disabling unnecessary web management interfaces, implementing network monitoring to detect unusual traffic patterns, and conducting regular security assessments of network infrastructure devices. Organizations should also establish incident response procedures specifically tailored to address potential exploitation of this vulnerability, including regular configuration audits and user awareness training to recognize potential phishing attempts that might exploit similar vulnerabilities. The vulnerability's classification as a stored XSS flaw emphasizes the importance of proper input validation and output encoding practices throughout the application development lifecycle, aligning with security frameworks such as OWASP Top 10 and NIST cybersecurity guidelines.
