Summary

CVE-2025-53912 is a critical-severity External Control of File Name or Path (CWE-73) vulnerability in Meddream Pacs Server. Its CVSS base score is 9.6 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 36th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-53912 is an arbitrary file read vulnerability in the encapsulatedDoc functionality of MedDream PACS Premium version 7.3.6.870. The issue allows a specially crafted HTTP request to trigger the vulnerability, enabling unauthorized access to files on the affected system. It has been assigned CWE-73 (External Control of File Name or Path) and a CVSS v3.1 base score of 9.6 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N), indicating high severity due to its network accessibility, low attack complexity, and significant impacts on confidentiality and integrity.

An attacker with low privileges, such as an authenticated user, can exploit this vulnerability remotely over the network without requiring user interaction. By sending a malicious HTTP request to the vulnerable endpoint, the attacker can read arbitrary files on the server, potentially exposing sensitive data like configuration files, user credentials, or medical records in a PACS environment. The scoped impact (S:C) amplifies the consequences within the security scope, while the high integrity impact (I:H) suggests potential for data tampering through file access.

Details on mitigation and patches are available in the Cisco Talos Intelligence advisory at https://talosintelligence.com/vulnerability_reports/TALOS-2025-2273. Security practitioners should consult this report for vendor-recommended updates or workarounds.

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly rejects or sanitizes untrusted path strings before they reach filesystem operations.

AC-3 Access Enforcement partial match

Enforces authorization checks on the actual resource accessed, blocking unauthorized files even when a malicious path is supplied.

AC-6 Least Privilege partial match

Least-privilege limits the set of files or directories any subject can affect, shrinking the blast radius of a path-control flaw.

PR.PS-06 full match
prevents

Secure SDLC practices include input validation and path sanitization that eliminate this weakness.

PR.AA-05 mostly match
prevents

Least-privilege file authorization directly limits damage from externally controlled paths.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect path-traversal issues but does not itself implement preventive controls.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and path-handling controls that directly prevent external file/path manipulation.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against untrusted input influencing file operations.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles discourage unsafe path construction but do not prescribe concrete file-name controls.

A.8.28 Secure coding partial match
prevents

Secure coding standards require canonicalization, allow-listing, and bounds checks on file paths, directly eliminating CWE-73.

A.8.3 Information access restriction partial match
mitigates

Information access restriction limits which files can be reached, indirectly reducing impact of path manipulation.
