Unauthenticated RCE in Hikvision Integrated Security Management Platform applyCT via Fastjson deserialization

IdentifiersCVE-2025-34067CWE-502· Deserialization of Untrusted Data

CVE-2025-34067 is an unauthenticated remote code execution vulnerability in the applyCT component of Hikvision Integrated Security Management Platform. According to the provided content, the /bic/ssoService/v1/applyCT endpoint deserializes untrusted user-supplied data using a vulnerable version of the Fastjson library. Because Fastjson auto-type can be abused to instantiate attacker-controlled classes, a remote attacker can supply crafted serialized input that references a malicious class over LDAP, causing the target to load arbitrary Java classes and execute attacker-controlled code on the underlying system. The issue is therefore a Java unsafe deserialization flaw in a network-reachable endpoint, with exploitation requiring no authentication. The content also states exploitation evidence was observed by the Shadowserver Foundation on 2025-02-05 UTC.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows unauthenticated remote code execution on the affected Hikvision management platform. An attacker could execute arbitrary commands on the host system, fully compromise the application server, access or manipulate surveillance-management data and functions, establish persistence, pivot further into connected environments, and potentially disrupt or take control of security-management operations.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, restrict or disable external access to the /bic/ssoService/v1/applyCT endpoint and avoid exposing the management platform directly to the internet. Place the system behind VPN or zero-trust access controls, limit access to trusted administrative networks, and monitor for suspicious requests to the applyCT endpoint and for outbound LDAP/RMI-style lookups from the server. Network segmentation around the management platform and egress filtering to block unnecessary directory/protocol lookups can reduce exploitability until patches are applied.

Remediation

Patch, then assume compromise.

Apply the vendor patch or fixed release for Hikvision Integrated Security Management Platform/HikCentral Professional that addresses CVE-2025-34067. The provided content indicates patches are available. Because the root cause is use of a vulnerable Fastjson version and unsafe deserialization behavior, remediation should include upgrading Fastjson to a non-vulnerable version and removing or disabling unsafe auto-type deserialization in the affected applyCT code path.
