o Equipment: Osprey Pump Controller
o Vulnerabilities: Insufficient Entropy, Use of GET Request Method with
Sensitive Query Strings, Use of Hard-coded Password, OS Command Injection,
Cross-site Scripting, Authentication Bypass using an Alternate Path or
Channel, Cross-Site Request Forgery, Command Injection
2. RISK EVALUATION
Successful exploitation of these vulnerabilities could allow an attacker to
gain unauthorized access, retrieve sensitive information, modify data, cause a
denial-of-service, and/or gain administrative control.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following version of Osprey Pump Controller, pumping systems, and automated
controls is affected:
o Osprey Pump Controller version 1.01
3.2 VULNERABILITY OVERVIEW
3.2.1 INSUFFICIENT ENTROPY CWE-331
Osprey Pump Controller version 1.01 is vulnerable to a predictable weak session
token generation algorithm and could aid in authentication and authorization
bypass. This could allow a cyber threat actor to hijack a session by predicting
the session id and gain unauthorized access to the product.
CVE-2023-28395 has been assigned to this vulnerability. A CVSS v3 base score of
8.3 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:R/S:U/
C:H/I:H/A:L ).
3.2.2 USE OF GET REQUEST METHOD WITH SENSITIVE QUERY STRINGS CWE-598
Osprey Pump Controller version 1.01 is vulnerable to an unauthenticated file
disclosure. Cyber threat actors could use a GET parameter to force the affected
device to disclose arbitrary files and sensitive system information.
CVE-2023-28375 has been assigned to this vulnerability. A CVSS v3 base score of
7.5 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:N/A:N ).
3.2.3 USE OF HARD-CODED PASSWORD CWE-259
Osprey Pump Controller version 1.01 has a hidden administrative account with a
hardcoded password that allows full access to the web management interface
configuration. The account is not visible in the Usernames and Passwords menu
list of the application and the password cannot be changed through any normal
operation of the device.
CVE-2023-28654 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
3.2.4 IMPROPER NEUTRALIZATION OF SPECIAL ELEMENTS USED IN AN OS COMMAND ('OS
COMMAND INJECTION') CWE-78
Osprey Pump Controller version 1.01 is vulnerable to an unauthenticated OS
command injection vulnerability. Threat actors could exploit this vulnerability
to inject and execute arbitrary shell commands through a HTTP POST parameter
called by index.php script.
CVE-2023-27886 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
3.2.5 IMPROPER NEUTRALIZATION OF SPECIAL ELEMENTS USED IN AN OS COMMAND ('OS
COMMAND INJECTION') CWE-78
Osprey Pump Controller version 1.01 is vulnerable an unauthenticated OS command
injection vulnerability. Threat actors could exploit this vulnerability to
inject and execute arbitrary shell commands through a HTTP GET parameter called
by DataLogView.php, EventsView.php and AlarmsView.php scripts.
CVE-2023-27394 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
3.2.6 IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION ('CROSS-SITE
SCRIPTING') CWE-79
Osprey Pump Controller version 1.01 inputs passed to a GET parameter are not
properly sanitized before being returned to the user. Threat actors could
exploit this vulnerability to execute arbitrary HTML/JS code in a user's
browser session in context of an affected site.
CVE-2023-28648 has been assigned to this vulnerability. A CVSS v3 base score of
7.5 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:N/I:H/A:N ).
3.2.7 AUTHENTICATION BYPASS USING AN ALTERNATE PATH OR CHANNEL CWE-288
Osprey Pump Controller version 1.01 could allow an unauthenticated user to
create an account and bypass authentication, thereby gaining unauthorized
access to the system. A threat actor could exploit this vulnerability to create
a user account without providing valid credentials. A threat actor who
successfully exploits this vulnerability could gain access to the pump
controller and cause disruption in operation, modify data, or shut down the
controller.
CVE-2023-28398 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:H/I:H/A:H ).
3.2.8 CROSS-SITE REQUEST FORGERY (CSRF) CWE-352
Osprey Pump Controller version 1.01 allows users to perform certain actions via
HTTP requests without performing any checks to verify the requests. This could
allow an unauthorized user to perform certain actions with administrative
privileges if a logged-in user visits a malicious website.
CVE-2023-28718 has been assigned to this vulnerability. A CVSS v3 base score of
7.1 has been calculated; the CVSS vector string is ( AV:N/AC:H/PR:L/UI:R/S:U/
C:H/I:H/A:H ).
3.2.9 IMPROPER NEUTRALIZATION OF SPECIAL ELEMENTS USED IN A COMMAND ('COMMAND
INJECTION') CWE-77
Osprey Pump Controller version 1.01 contains an unauthenticated command
injection vulnerability that could allow system access with www-data
permissions.
CVE-2023-28712 has been assigned to this vulnerability. A CVSS v3 base score of
8.2 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:N/UI:N/S:U/
C:L/I:H/A:N ).
3.3 BACKGROUND

3.4 RESEARCHER
Gjoko Krstic of Zero Science Lab reported these vulnerabilities to CISA.
4. MITIGATIONS
ProPump and Controls has not responded to requests to work with CISA to
mitigate the reported vulnerabilities. Users of the affected product are
encouraged to contact ProPump and Controls representative .
CISA recommends users take defensive measures to minimize the risk of
exploitation of these vulnerabilities. Specifically, users should:
o Minimize network exposure for all control system devices and/or systems,
and ensure they are not accessible from the Internet .
o Locate control system networks and remote devices behind firewalls and
isolate them from business networks.
o When remote access is required, use secure methods, such as Virtual Private
Networks (VPNs), recognizing VPNs may have vulnerabilities and should be
updated to the most current version available. Also recognize VPN is only
as secure as its connected devices.
CISA reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices
on the ICS webpage at cisa.gov/ics . Several CISA products detailing cyber
defense best practices are available for reading and download, including
Improving Industrial Control Systems Cybersecurity with Defense-in-Depth
Strategies .
Additional mitigation guidance and recommended practices are publicly available
on the ICS webpage at cisa.gov/ics in the technical information paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies .
Organizations observing suspected malicious activity should follow established
internal procedures and report findings to CISA for tracking and correlation
against other incidents.
