CVE-2026-32839 in GS-5008PL
Summary
by MITRE • 03/18/2026
Edimax GS-5008PL firmware version 1.00.54 and prior contain a cross-site request forgery vulnerability that allows remote attackers to perform unauthorized administrative actions by inducing logged-in administrators to visit malicious pages. Attackers can exploit the lack of anti-CSRF tokens and request validation to change passwords, upload firmware, reboot the device, perform factory resets, or modify network configurations.

The vulnerability identified as CVE-2026-32839 affects the Edimax GS-5008PL network switch firmware version 1.00.54 and earlier releases, presenting a critical cross-site request forgery weakness that undermines the device's administrative security posture. This flaw resides in the web-based management interface of the network switch, which fails to implement proper anti-cross-site request forgery mechanisms. The vulnerability stems from the absence of anti-CSRF tokens and insufficient request validation within the administrative functions, creating a pathway for malicious actors to exploit the device's administrative capabilities without proper authorization.
The technical implementation of this vulnerability allows remote attackers to manipulate the device's administrative functions through carefully crafted malicious web pages that trigger unauthorized actions when viewed by authenticated administrators. The lack of anti-CSRF tokens means that legitimate administrative requests cannot be distinguished from forged requests, while the absence of proper request validation enables attackers to submit unauthorized commands through HTTP requests. This vulnerability specifically impacts the device's ability to authenticate administrative actions, as the web interface does not verify the origin or legitimacy of requests originating from the administrative interface. The flaw permits attackers to execute a range of administrative functions including password changes, firmware uploads, device reboots, factory resets, and network configuration modifications, all without requiring valid credentials or authentication.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it enables attackers to completely compromise the device's administrative control and potentially disrupt network operations. When an authenticated administrator visits a malicious page, the attacker can perform actions that may lead to network downtime, unauthorized access to network resources, or complete device compromise. The vulnerability affects the device's integrity and availability, as attackers can perform factory resets that erase all configurations, upload malicious firmware that could provide persistent backdoors, or modify network settings to redirect traffic or disable security features. This represents a significant threat to network infrastructure security, as the compromised device can serve as a foothold for broader network attacks or provide attackers with insights into the network topology and configuration.
The vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications and network devices. The flaw demonstrates how network infrastructure devices often lack proper security controls that are standard in web applications, creating a gap in security posture that attackers can exploit. From an attack perspective, this vulnerability maps to multiple ATT&CK techniques including T1078 for valid accounts and T1566 for social engineering, as attackers must convince administrators to visit malicious pages. The lack of proper CSRF protection in network devices represents a common oversight in embedded systems security, where the focus on network connectivity often overshadows the importance of web interface security controls. Organizations should consider implementing network segmentation, access controls, and regular security assessments to mitigate risks associated with such vulnerabilities in network infrastructure devices. The remediation requires firmware updates that implement proper anti-CSRF token mechanisms and request validation, ensuring that administrative requests can only be processed when originated from legitimate administrative interfaces rather than external malicious pages.
