CVE-2022-25344 in d-COLOR MF3555
Summary
by MITRE • 04/20/2022
An XSS issue was discovered on Kyocera d-COLOR MF3555 2XD_S000.002.271 devices. The Web Application doesn't properly check parameters, sent in a /dvcset/sysset/set.cgi POST request via the arg01.Hostname field, before saving them on the server. In addition, the JavaScript malicious content is then reflected back to the end user and executed by the web browser.

The vulnerability CVE-2022-25344 represents a cross-site scripting flaw in Kyocera d-COLOR MF3555 2XD_S000.002.271 multifunction devices that stems from inadequate input validation within the web application interface. This issue specifically affects the /dvcset/sysset/set.cgi endpoint where the arg01.Hostname parameter is processed without proper sanitization or validation checks. The vulnerability falls under CWE-79 which categorizes improper neutralization of input during web page generation, making it a classic example of reflected cross-site scripting that can be exploited by malicious actors to inject client-side scripts into web pages viewed by other users.
The technical exploitation of this vulnerability occurs when an attacker crafts a malicious payload and sends it through the hostname parameter in a POST request to the vulnerable set.cgi endpoint. The device fails to validate or sanitize the input before storing it in its configuration, allowing malicious JavaScript code to be persisted in the system. When subsequent users access the web interface or view pages that display this stored hostname value, the malicious script is executed in their browser context, creating a reflected XSS attack vector. This type of vulnerability is particularly dangerous because it leverages the trust relationship between the user and the web application, allowing attackers to execute arbitrary code in the victim's browser.
The operational impact of this vulnerability extends beyond simple script execution as it can enable attackers to perform a wide range of malicious activities including session hijacking, credential theft, and data exfiltration. Attackers could potentially redirect users to malicious websites, steal administrative credentials, or even gain deeper access to the device's internal systems through the compromised web interface. The vulnerability affects the device's administrative web console, which could provide attackers with access to device configuration settings, user management capabilities, and potentially sensitive network information. This risk is amplified because the device is likely to be accessible from within corporate networks, making it a potential stepping stone for lateral movement attacks.
Organizations should implement immediate mitigations including input validation and output encoding for all parameters received through the web interface, particularly those used for configuration settings. Network segmentation and access controls should be enforced to limit exposure of the device to untrusted networks. The device firmware should be updated to the latest version provided by Kyocera, as this vulnerability is likely to be addressed through proper input sanitization and validation mechanisms. Additionally, web application firewalls and intrusion detection systems should be configured to monitor for suspicious POST requests containing potentially malicious script content. This vulnerability aligns with ATT&CK technique T1566 which involves the use of malicious payloads delivered through web interfaces, and represents a critical security gap that requires immediate attention to prevent potential compromise of network infrastructure.
