Security readout for executives and security teams
Plain-English summary
CVE-2025-7958 is a high-severity code injection issue in Trellix Network Security products. The reported path requires a locally authenticated administrator using the web interface, which limits broad internet-scale risk but creates serious impact if an admin account or management network is compromised.
Executive priority
Prioritize this for environments using affected Trellix Network Security management systems. The attacker needs admin-level access, but the business impact can be severe because arbitrary code execution may affect security monitoring infrastructure.
Technical view
The vulnerability is CWE-94 code injection. Sources state a locally authenticated admin user can execute arbitrary code through the web interface using Alert artifact details. CVSS 4.0 score is 7.1, with high confidentiality, integrity, and availability impact, high privileges required, and adjacent attack vector.
Likely exposure
Organizations running Trellix Network Security NX, EX, FX, AX, or CMS version 10.0.4 should assess exposure. Default status is listed as unaffected outside the specified affected version, but confirm against Trellix guidance.
Exploitation context
The provided sources do not show CISA KEV listing or confirmed active exploitation. Exploitation requires high privileges, but successful abuse could allow arbitrary code execution on affected systems.
Researcher notes
Evidence is limited to the CVE record and Trellix advisory reference. The CVE title mentions CM and NX, while affected data lists NX, EX, FX, AX, and CMS version 10.0.4. Treat vendor advisory as authoritative for product naming and remediation.
Mitigation direction
- Review Trellix advisory 000015433 for official remediation guidance.
- Identify any Trellix Network Security systems running version 10.0.4.
- Restrict management web interface access to trusted administration networks.
- Audit and minimize administrator accounts on affected systems.
- Monitor Trellix updates for patch or workaround details.
Validation and detection
- Inventory Trellix Network Security NX, EX, FX, AX, and CMS deployments.
- Confirm software version and compare with affected version 10.0.4.
- Review administrator account activity for unusual web interface use.
- Check logs for suspicious Alert artifact detail access by admins.
- Verify remediation status against Trellix advisory 000015433.

Improper Control of Generation of Code ('Code Injection')
Improper Control of Generation of Code ('Code Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
