A security flaw has been discovered in Xinhu Rainrock RockOA up to version 2.7.1. This vulnerability allows cross-site scripting (XSS) attacks through an unknown function of the file rock_page_gong.php, specifically when manipulating the argument fengmian. The attack can be launched remotely, and as the exploit has been released to the public, it may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
The CVSS score for this vulnerability is 2, indicating a low severity level. This score reflects the ease with which an attacker can exploit the vulnerability, which is characterized by a low attack complexity and the requirement for user interaction. Organizations are advised to assess their risk based on the potential impact of this vulnerability.
Risk to organizations includes potential unauthorized access and manipulation of web content, which could lead to further attacks or exploitation. While the overall risk is low, organizations should prioritize patching to prevent any exploitation.
Organizations should address this vulnerability in their patch cycle, as it has been publicly disclosed and may be exploited by attackers in the wild.
To mitigate risks associated with this vulnerability, organizations should ensure that they have the latest patches applied and conduct regular security assessments to identify potential weaknesses.
Vulnerability Details
The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-94 (Improper Control of Generation of Code). It affects the RockOA product, specifically the Cover Image Handler component, up to version 2.7.1.
The vulnerability was published on January 5, 2026, and has been analyzed by the vendor. The attack vector is over the network, with a low attack complexity and low privileges required. The attack requires user interaction, which may increase the likelihood of exploitation.
Technical Analysis
The root cause of the vulnerability lies in improper handling of user input in the rock_page_gong.php file. This oversight allows attackers to inject malicious scripts into web pages served to other users. The functionality of the application fails to adequately sanitize input, leading to potential XSS attacks. The attack complexity is low, meaning that an attacker can exploit this vulnerability without requiring advanced technical skills.
The attack vector is network-based, allowing remote exploitation. Privileges required are low, meaning that unauthenticated users might be able to execute an attack if they can interact with the vulnerable component. User interaction is required, as the victim must visit the manipulated URL for the attack to succeed.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability includes potential unauthorized access to sensitive user data or web content manipulation. If exploited, this vulnerability could allow attackers to conduct phishing attacks, deploy malware, or perform other malicious actions utilizing the compromised application.
The potential blast radius is significant as it can affect all users interacting with the vulnerable application. Organizations should assess their exposure and prioritize this vulnerability in their patch management processes.
Given the CVSS score of 2 and the absence from the KEV catalog, organizations should schedule remediation during their routine maintenance cycles. However, due to its public disclosure, organizations should remain vigilant for any signs of exploitation.
