Security readout for executives and security teams
Plain-English summary
CVE-2025-0645 affects Narkom Pyxis Signage through 31012025. A highly privileged user may be able to upload dangerous file types and reach functionality not properly constrained by access controls. The business risk is serious because confidentiality, integrity, and availability are all rated high if exploited.
Executive priority
Prioritize identification and vendor-guidance review for any Pyxis Signage deployment. Treat internet-exposed or broadly administered systems as higher urgency, especially where privileged account security is weak.
Technical view
The CVE describes CWE-434, unrestricted upload of a file with a dangerous type, in Pyxis Signage. CVSS 3.1 is 7.2: network-accessible, low complexity, high privileges required, no user interaction, unchanged scope, and high CIA impact. Public details do not name a specific fixed version or patch.
Likely exposure
Organizations using Narkom Pyxis Signage versions through 31012025 should treat systems as potentially affected. Exposure is most relevant where administrator or other high-privilege access to upload functionality is available over a network.
Exploitation context
The source bundle does not indicate CISA KEV listing or active exploitation. The high-privilege requirement reduces broad opportunistic risk, but compromised admin accounts or insider misuse could make the issue impactful.
Researcher notes
Evidence is limited to the CVE record and Turkish advisory references. One USOM reference is marked broken in the bundle. The affected data includes “versions: 0,” while the description states affected through 31012025; rely on vendor/government advisories for final version mapping.
Mitigation direction
- Check Narkom and Turkish government advisories for fixed-version or workaround guidance.
- Inventory Pyxis Signage deployments and identify versions through 31012025.
- Restrict administrative and upload access to trusted networks and accounts.
- Review privileged accounts and remove unnecessary access to signage administration.
- Monitor for vendor updates before relying on compensating controls as a fix.
Validation and detection
- Confirm whether Pyxis Signage is deployed in the environment.
- Record installed version and compare against “through 31012025.”
- Review who can access file upload or signage administration functions.
- Check logs for unusual uploads by privileged users.
- Track the USOM/Siber Güvenlik advisory pages for remediation updates.

Unrestricted Upload of File with Dangerous Type
Unrestricted Upload of File with Dangerous Type represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
