Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Osprey Pump Controller version 1.01 contains an unauthenticated file disclosure vulnerability tracked as CVE-2023-28375. The flaw, assigned CWE-552, allows an attacker to supply a GET parameter that retrieves arbitrary files from the device, exposing sensitive configuration data and system information. It carries a CVSS 3.1 score of 7.5 reflecting network attack vector, low complexity, and no required authentication or user interaction.
An unauthenticated remote attacker can exploit the issue over the network to read any file accessible to the application, resulting in disclosure of credentials, configuration details, or other sensitive material without affecting integrity or availability. The vulnerability affects the web interface of the pump controller and requires no prior access or privileges.
CISA has released ICS advisory ICSA-23-082-06 that addresses the affected Osprey Pump Controller and provides guidance for asset owners.
EPSS for the CVE rose from a low baseline to a peak of 0.1516 before settling at the current value of 0.1087, indicating measurable exploitation interest after public disclosure.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Controls on authorized publication limit files and directories with nonpublic data from becoming accessible to external parties.
Controlling and documenting P2P file sharing prevents files and directories from being made accessible to external parties for unauthorized distribution.
Identifying and documenting file and directory locations allows restriction of access to external parties.
Protecting backup files ensures they are not accessible to external parties or unauthorized spheres.
Sanitizing equipment before off-site maintenance reduces the risk of files or directories containing sensitive data becoming accessible to external parties.
Policy restricts media access to authorized parties only, preventing exposure of resources to external or unauthorized actors.
Media access restrictions prevent files or directories from being accessible to external parties.
Employing and evaluating controls at documented alternate sites makes files and directories less likely to be accessible to external parties through physical or environmental weaknesses.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Enforcing least-privilege permissions and authorization policies directly prevents unauthorized file/directory exposure.
Data-at-rest protections such as encryption or ACLs reduce the impact of unintended file exposure.
Logical segmentation and access protections stop external parties from reaching files that should remain internal.
Hardened configuration baselines commonly include file-system permission settings that limit external access.
