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).

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:
- Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet.
- Locate control system networks and remote devices behind firewalls and isolate them from business networks.
- 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.
