CVE-2024-7828
Overview
This vulnerability is a buffer overflow caused by improper handling of the album_name argument within the cgi_set_cover function of the /cgi-bin/photocenter_mgr.cgi component. The flaw arises from insufficient bounds checking on user-supplied input, allowing memory corruption in the affected D-Link DNS-120 firmware and related models. The vulnerable code path processes HTTP CGI requests, specifically manipulating album metadata.
Vulnerability Description
** UNSUPPORTED WHEN ASSIGNED ** A vulnerability classified as critical was found in D-Link DNS-120, DNR-202L, DNS-315L, DNS-320, DNS-320L, DNS-320LW, DNS-321, DNR-322L, DNS-323, DNS-325, DNS-326, DNS-327L, DNR-326, DNS-340L, DNS-343, DNS-345, DNS-726-4, DNS-1100-4, DNS-1200-05 and DNS-1550-04 up to 20240814. This vulnerability affects the function cgi_set_cover of the file /cgi-bin/photocenter_mgr.cgi. The manipulation of the argument album_name leads to buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed that the product is end-of-life. It should be retired and replaced.
Impact
An attacker with network access and low privileges can remotely exploit this vulnerability without user interaction to execute arbitrary code, modify system behavior, or cause denial of service by crashing the device. The CVSS vector indicates no user interaction (UI:N) is required, and the attack complexity is low (AC:L), making exploitation feasible over the network. Successful exploitation could lead to full compromise of the device, impacting data confidentiality, integrity, and availability in environments relying on these NAS devices.
Solution
No official patches or updates are available as the affected D-Link products are end-of-life and unsupported. The vendor has confirmed product retirement and recommends discontinuing use and replacing the affected devices. For detailed information, refer to the advisory at https://vuldb.com/?id.274726. Organizations should prioritize decommissioning these models to mitigate exposure.

Full Analysis
A critical vulnerability has been identified in several D-Link network storage and surveillance products, specifically affecting the function cgi_set_cover within the file /cgi-bin/photocenter_mgr.cgi. This vulnerability arises from improper handling of the argument album_name, leading to a buffer overflow condition. When an attacker manipulates this argument, they can potentially overwrite memory locations, which may allow for arbitrary code execution. The severity of this vulnerability is underscored by its high CVSS score of 9.8, indicating a significant risk to systems utilizing these affected devices.
The attack vector for this vulnerability is particularly concerning due to its remote exploitability. An attacker does not need physical access to the device; instead, they can initiate the attack over the network. Given that the affected products are no longer supported by the vendor, there are no patches or updates available to mitigate this risk. This lack of support not only increases the likelihood of exploitation but also raises the stakes for organizations still utilizing these devices, as they may be unaware of the potential threats posed by their outdated technology.
In terms of real-world impact, the exploitation of this vulnerability can lead to severe consequences for businesses. Successful attacks could result in unauthorized access to sensitive data stored on the affected devices, disruption of services, or even complete system compromise. Organizations relying on these products for data storage or surveillance may face reputational damage, regulatory penalties, and financial losses. Additionally, the public disclosure of this vulnerability increases the urgency for organizations to act, as malicious actors are likely to develop and deploy exploits in the wild.
To detect and mitigate the risks associated with this vulnerability, organizations should first conduct an inventory of their networked devices to identify any affected D-Link products. Regular vulnerability assessments and penetration testing can help uncover potential weaknesses in their systems. Given the end-of-life status of these devices, the most effective long-term strategy is to replace them with supported alternatives that receive regular security updates. In the interim, organizations can implement network segmentation to limit exposure, employ intrusion detection systems to monitor for unusual activity, and enforce strict access controls to minimize the risk of exploitation.
In conclusion, the critical vulnerability affecting various D-Link products presents a significant threat to organizations still utilizing these devices. With the potential for remote exploitation and the absence of vendor support, the risk of data breaches and operational disruptions is heightened. Organizations must take proactive steps to identify affected devices, assess their risk posture, and implement appropriate mitigation strategies to safeguard their networks and sensitive information. Transitioning to supported products is essential for maintaining a robust security posture in an increasingly hostile cyber landscape.
CSURFACE threat intelligence has identified a significant increase in the Exploit Prediction Scoring System (EPSS) score for CVE-2024-7828, rising by over one-third to a current level that places it near the top percentile of predicted exploit likelihood. This upward adjustment indicates growing confidence within the threat landscape that adversaries may actively target this critical buffer overflow vulnerability in D-Link devices. Although no new exploit code or active exploitation campaigns have been detected by our telemetry, the elevated EPSS score reflects heightened risk perception based on factors such as increased scanning activity or emerging exploit frameworks observed indirectly. For defenders, this shift underscores the urgency of reassessing exposure to affected devices, as the probability of exploitation attempts is materially higher than previously assessed. Consequently, the overall threat level for CVE-2024-7828 has escalated from a theoretical concern to a more imminent risk, warranting increased vigilance despite the absence of confirmed exploit deployments at this time.
