Executive Summary

[{'type': 'paragraph', 'content': "CVE-2026-3026 is a server-side request forgery (SSRF) vulnerability found in erzhongxmu JEEWMS version 3.7, specifically in the UEditor component's file /plug-in/ueditor/jsp/getRemoteImage.jsp."}, {'type': 'paragraph', 'content': "The vulnerability occurs because the 'upfile' argument is improperly handled, allowing an attacker to manipulate it and cause the server to make unauthorized requests to arbitrary URLs."}, {'type': 'paragraph', 'content': 'This flaw enables remote attackers to exploit the system without authentication by coercing the server into making unintended HTTP requests, potentially accessing internal resources or performing other malicious actions.'}] [1, 2]

Impact Analysis

Exploitation of this vulnerability can lead to unauthorized internal network scanning and disclosure of sensitive information.

Attackers can interact with internal services that are normally inaccessible from outside the network, potentially compromising the confidentiality, integrity, and availability of the affected system.

Since the attack can be initiated remotely without authentication, it poses a significant risk to the security posture of the affected environment.

Detection Guidance

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by identifying if the affected endpoint /plug-in/ueditor/jsp/getRemoteImage.jsp is accessible and vulnerable to server-side request forgery via the "upfile" parameter.'}, {'type': 'paragraph', 'content': 'One method to detect vulnerable targets is by using Google dorking with the query: inurl:plug-in/ueditor/jsp/getRemoteImage.jsp'}, {'type': 'paragraph', 'content': 'To test on your system, you can attempt to send crafted HTTP requests to the endpoint with manipulated "upfile" parameters to see if the server makes unintended requests. For example, using curl:'}, {'type': 'list_item', 'content': 'curl -v "http://[target]/plug-in/ueditor/jsp/getRemoteImage.jsp?upfile=http://example.com"'}, {'type': 'paragraph', 'content': 'Monitoring outgoing HTTP requests from your server to unexpected or internal IP addresses after such tests can also help detect exploitation attempts.'}] [1]

Mitigation Strategies

No known mitigations or countermeasures have been published for this vulnerability.

It is suggested to replace the affected component (UEditor in JEEWMS 3.7) with an alternative product that does not contain this vulnerability.

As an immediate step, restrict access to the vulnerable endpoint /plug-in/ueditor/jsp/getRemoteImage.jsp via firewall rules or web server configuration to prevent external access.

Monitor network traffic for unusual outbound requests initiated by the server that could indicate exploitation attempts.
