Summary

CVE-2025-3425 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Philips (inferred from references). Its CVSS base score is 7.3 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

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

The vulnerability is a deserialization flaw (CWE-502) in the Philips IntelliSpace Portal application, versions 12 and prior. It stems from the use of .NET Remoting on port 755 with the TypeFilterLevel configuration set to Full, which permits unsafe deserialization of untrusted data and can result in remote code execution.

An attacker with adjacent-network access can exploit the issue by supplying crafted serialized payloads over the exposed port. Successful exploitation grants the ability to execute arbitrary code on the affected server, with high impact to confidentiality, integrity, and availability under the reported CVSS 7.3 vector.

Philips has published security advisories addressing the flaw, available via their security advisories page. The EPSS score rose from a low baseline to a peak of 0.0336, indicating that exploitation interest emerged after disclosure.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can uncover deserialization flaws before deployment.

Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.

Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.

Integrity verification tools can detect malformed or tampered serialized data after the fact.

PR.PS-02 none match
prevents

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.

finds

Security testing includes validation of deserialization routines and the use of untrusted data, reducing the likelihood that unsafe object reconstruction will be deployed.

prevents

Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.

finds

Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.
