Dayrui XunRuiCMS Stored Cross-Site Scripting Vulnerability in Friendly Links Component

A stored cross-site scripting vulnerability has been identified in Dayrui XunRuiCMS versions through 4.6.3. This issue arises in the Friendly Links Handler, where the Website Address input is not properly sanitized before being displayed. As a result, an attacker can inject malicious scripts that are executed when the link is viewed. The vulnerability can be exploited remotely, but requires authentication and user interaction.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user.

Reproduction

To reproduce this vulnerability, log into Dayrui XunRuiCMS version 4.6.3 and navigate to the 'Website Information - Friendly Links' section. Here, input a Unicode-encoded payload into the 'Website Address' field. The system's inability to properly decode and sanitize this input will trigger the stored XSS vulnerability, as the injected script will be executed when the link is accessed.
