Assigner: CERT VDE

Description
An XSS vulnerability in pxc_portCntr2.php can be used by an unauthenticated remote attacker to trick an authenticated user to send a manipulated POST request to the device in order to change parameters available via web based management (WBM). The vulnerability does not provide access to system-level resources such as operating system internals or privileged functions. Access is limited to device configuration parameters that are available in the context of the web application. The session cookie is secured by the httpOnly Flag. Therefore an attacker is not able to take over the session of an authenticated user.

Mitigation Strategies

To mitigate this vulnerability, ensure that users are cautious about interacting with untrusted links or POST requests that could manipulate device parameters via the web-based management interface. Since the vulnerability affects firmware versions prior to a certain update, applying the latest firmware updates from the vendor that address this issue is recommended. Additionally, restrict access to the web management interface to trusted users only and monitor for unusual configuration changes.

Executive Summary

This vulnerability is a Cross-Site Scripting (XSS) issue in the pxc_portCntr2.php component. An unauthenticated remote attacker can exploit it to trick an authenticated user into sending a manipulated POST request to the device. This allows the attacker to change device configuration parameters accessible via the web-based management interface. However, the vulnerability does not allow access to system-level resources or privileged functions, and the session cookie is protected by the httpOnly flag, preventing session hijacking.

Impact Analysis

The vulnerability can impact you by allowing an attacker to modify device configuration parameters through the web-based management interface without needing system-level access. This could lead to unauthorized changes in device settings, potentially affecting device behavior or security. However, it does not allow the attacker to gain control over the system or access privileged functions.
