Edimax GS-5008PL firmware version 1.00.54 and prior contains a stored cross-site scripting vulnerability in the system_name_set.cgi script. This vulnerability allows attackers to inject arbitrary script code by manipulating the sysName parameter. To exploit this vulnerability, an attacker can send a crafted POST request containing malicious script payloads. Once injected, these scripts execute when management pages, including system_data.js, are viewed by administrators.
With a CVSS score of 5.1, this vulnerability is classified as medium severity. The low complexity of the attack and the requirement for low privileges make it accessible for potential exploitation. Organizations using affected firmware versions should recognize the implications of this vulnerability.
Risk to organizations includes unauthorized script execution, which could lead to data breaches or system compromises. Given the nature of the vulnerability, it is crucial for organizations to prioritize patching immediately to mitigate the risk of exploitation.
Currently, there is no evidence of active exploitation in the wild. However, organizations should remain vigilant and monitor their systems for any unusual activity that could indicate an attempted exploit of this vulnerability.
Immediate action is required by organizations to address this vulnerability to ensure the security and integrity of their systems.
Vulnerability Details
The Edimax GS-5008PL firmware versions affected by this vulnerability extend to all versions prior to 1.00.54. The nature of the vulnerability falls under the CWE-79 classification, which denotes stored cross-site scripting issues. It is essential to understand that the vulnerability can be exploited through network access, with the attack complexity rated as low.
Technical Analysis
The root cause of this vulnerability lies in the improper validation of user input for the sysName parameter, which is susceptible to script injection. Attackers can leverage this by sending crafted POST requests to the affected script, leading to the execution of arbitrary scripts when the management interface is accessed by an administrator.
The attack vector is classified as network-based, indicating that an attacker can exploit this vulnerability remotely. The attack complexity is low, meaning that it can be successfully executed without specialized knowledge or extensive resources.
In terms of privilege requirements, the attacker only needs low-level access, while user interaction is required to view the affected management pages where the scripts will execute. The impacts on confidentiality and integrity are rated as low, with no impact on availability.
Risk & Impact Analysis
The real-world deployment risk of this vulnerability is significant, especially for organizations that rely on the Edimax GS-5008PL for critical operations. The potential for unauthorized script execution poses a serious threat to data integrity and confidentiality.
Organizations should assess their exposure and determine the urgency of remediation based on the CVSS score of 5.1. Given the low complexity and potential for exploitation, organizations should address this vulnerability in their priority patch cycle.
