Executive Summary

CVE-2026-0588 is a cross-site scripting (XSS) vulnerability in Xinhu Rainrock RockOA up to version 2.7.1, specifically in the API component file rockfun.php. The vulnerability occurs because the 'callback' parameter is not properly sanitized before being included in the web page output. This allows an attacker to inject malicious JavaScript code remotely by manipulating the 'callback' argument, which can then execute in the victim's browser. The vulnerability requires user interaction to be exploited and bypasses the Same-Origin Policy, enabling arbitrary script execution. [1, 2]

Impact Analysis

This vulnerability can allow attackers to execute arbitrary JavaScript code in the context of the victim's browser. This can lead to theft of sensitive information, such as session tokens or credentials, and can be used to perform attacks against administrators or other users. Because the attack can be initiated remotely and requires user interaction, it poses a risk of data compromise and unauthorized actions within the affected application. [1, 2]

Detection Guidance

This vulnerability can be detected by checking for the presence of the vulnerable file rockfun.php in Xinhu Rainrock RockOA version up to 2.7.1 and testing the 'callback' parameter for improper handling. One method is to send a crafted HTTP request to the API endpoint with a malicious 'callback' parameter and observe if the response reflects the injected script. For example, you can use curl to test the vulnerability: curl -i "http://[target]/api.php?callback=<script>alert('xss_test')</script>". If the response includes the script tag without proper escaping, the system is vulnerable. Additionally, attackers may locate vulnerable targets using Google dorking with the query: inurl:rockfun.php. [1, 2]

Mitigation Strategies

Immediate mitigation steps include replacing or upgrading the affected product or component, as no official vendor patch or countermeasure has been reported. As a temporary workaround, you can implement input validation and sanitization on the 'callback' parameter to prevent script injection. Restricting access to the vulnerable API endpoint and monitoring for suspicious requests may also help reduce risk until a proper fix is applied. [1]
