Security readout for executives and security teams
Plain-English summary
CVE-2025-34067 is a critical unauthenticated remote code execution issue in Hikvision Integrated Security Management Platform. A vulnerable applyCT service can process unsafe data in a way that may let an attacker run commands on the server. For organizations using this platform, exposed management interfaces should be treated as high urgency.
Executive priority
Treat this as an urgent exposure-management item for any Hikvision security management platform in use. The combination of unauthenticated access, remote code execution, critical CVSS, and reported exploitation evidence warrants rapid inventory, containment, and vendor-guided remediation.
Technical view
The issue is unsafe Fastjson deserialization in /bic/ssoService/v1/applyCT. Untrusted input can trigger auto-type class loading and remote code execution on the underlying Java system. The bundle identifies CWE-502 and CVSS 4.0 score 10.0. Product and version detail is limited.
Likely exposure
Exposure is most likely where Hikvision Integrated Security Management Platform is reachable from the internet or broad internal networks. The source bundle only names version "0" and default status "unaffected," so asset validation against vendor guidance is necessary.
Exploitation context
The bundle says Shadowserver observed exploitation evidence on 2025-02-05 UTC and includes an exploit-tagged public reference. It is not marked as CISA KEV in the supplied data, so current active exploitation should not be assumed from this bundle alone.
Researcher notes
The strongest evidence is the CVE record, CVSS 10.0 vector, CWE-502 classification, and exploit-linked public references. The bundle does not provide a named vendor patch, precise affected version range, or KEV listing. Avoid assuming broader Hikvision product impact.
Mitigation direction
- Identify all Hikvision Integrated Security Management Platform deployments and owners.
- Check Hikvision guidance for fixed versions or official mitigations.
- Restrict platform access to trusted admin networks only.
- Block public access to the applyCT endpoint where operationally safe.
- Monitor for suspicious requests to /bic/ssoService/v1/applyCT.
- Prioritize isolation if patch status cannot be confirmed.
Validation and detection
- Search asset inventory for Hikvision Integrated Security Management Platform.
- Confirm whether /bic/ssoService/v1/applyCT is reachable externally.
- Review logs for suspicious applyCT requests around and after 2025-02-05.
- Confirm installed version and Fastjson dependency status with vendor documentation.
- Verify compensating controls restrict unauthenticated access.
- Document patch or mitigation evidence for each instance.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
