A Threat That Goes Beyond Cyberspace
A new zero-day vulnerability has emerged in Hikvision’s widely deployed applyCT platform, a key component of the company’s HikCentral Integrated Security Management ecosystem. The flaw, tracked as CVE-2025-34067, carries the maximum severity rating (CVSS 10), highlighting the immense threat it poses to governments, industries, and corporations relying on Hikvision for centralized surveillance and security management. The discovery has triggered widespread concern as it allows unauthenticated remote code execution (RCE) — a rare and highly dangerous exploit.
Global Exposure Through a Single Endpoint
This vulnerability stems from the use of an outdated and unsafe version of the Fastjson Java library within the applyCT module. The flaw is specifically linked to Fastjson’s “auto-type” feature, a deserialization mechanism that, when left unchecked, allows attackers to insert malicious code. Exploitation occurs via the exposed /bic/ssoService/v1/applyCT endpoint, where attackers can send a crafted JSON payload. This payload tricks the platform into deserializing a rogue Java class — JdbcRowSetImpl — which then connects to a remote LDAP server under the attacker’s control.
What makes this flaw especially alarming is the fact that no authentication is required. That means any exposed system, accessible over the internet, can be hijacked. Once breached, threat actors can execute arbitrary commands, hijack camera feeds, tamper with access controls, or use the platform as a foothold for further lateral movement inside the network.
Real-World Consequences and Defensive Measures
Hikvision’s applyCT is central to the operations of many high-security facilities, enabling integrated control over video surveillance, access management, intercoms, and alarms. This means the vulnerability isn’t just about stolen data — it’s a physical security threat, capable of disabling security protocols or exposing sensitive environments to real-world breaches.
Security experts have issued urgent mitigation steps for organizations using affected versions of applyCT or any HikCentral derivative:
Audit systems for exposure of the vulnerable endpoint `/bic/ssoService/v1/applyCT`
Update Fastjson to a secure version and apply all relevant Hikvision patches
Restrict internet access to the platform where possible
Monitor network logs for suspicious LDAP traffic, which may signal exploitation attempts
Failure to act swiftly can lead to unauthorized access, operational shutdowns, data leaks, financial damage, and reputational fallout. The widespread adoption of Hikvision products globally means that this threat is not isolated — it’s systemic.
What Undercode Say:
Understanding the Root of the Exploit
At the core of this vulnerability lies a fundamental issue: dependency mismanagement. The use of an outdated and insecure version of Fastjson, particularly with the “auto-type” feature enabled, is a recurring pattern in enterprise Java applications. What makes this situation critical is the context — Hikvision isn’t a web app processing casual user data; it’s a backbone for physical security systems. When deserialization flaws intersect with physical access, the consequences transcend digital boundaries.
Why Unauthenticated Access Escalates the Risk
In the cybersecurity world, an exploit that requires no login credentials and can be executed remotely is the worst-case scenario. This is particularly dangerous for systems like applyCT, often connected to sensitive infrastructures — prisons, airports, energy facilities, and corporate campuses. Remote execution through exposed APIs without login adds a nation-state level risk.
A Larger Conversation on Secure Coding
This incident reignites a broader industry conversation around secure coding practices. The “auto-type” issue in Fastjson has been public knowledge for years. Any critical system that continues to use unsafe default configurations essentially sets itself up for compromise. The lack of proactive code auditing or dependency scanning reflects poorly on vendors responsible for national or industrial security frameworks.
Surveillance and IoT: A Growing Attack Surface
As more organizations adopt integrated surveillance and IoT-based control systems, the attack surface has widened. What was once a closed-circuit camera setup is now a fully connected smart environment, often lacking robust segmentation or firewall policies. The applyCT platform, being central to these operations, offers a single point of failure — if it’s breached, attackers can control doors, cameras, alarms, and more.
How Organizations Should Respond Strategically
Mitigating this vulnerability is more than a quick patch job. Organizations must:
Establish automated patch management
Conduct penetration testing
Set up real-time alerting on abnormal traffic, especially over LDAP or JSON endpoints
Isolate their security management tools from open internet unless absolutely necessary
Furthermore, an internal review of third-party dependencies across the software stack is essential. This is not a Hikvision-only problem; it’s a software supply chain vulnerability that could affect countless platforms using Fastjson or similar libraries.
Implications for National Security
Given the widespread deployment of Hikvision products in critical infrastructure across the globe — including ports, energy sectors, government buildings — this is no longer just a corporate IT issue. Governments need to assess whether these platforms should be shielded behind air-gapped or highly segmented networks. Strategic adversaries could exploit this flaw not just for data theft, but to sabotage physical systems.
🔍 Fact Checker Results:
✅ CVE-2025-34067 is officially listed with a CVSS 10 rating
✅ Exploitation does not require authentication
✅ Vulnerability resides in the outdated use of Fastjson’s auto-type feature
📊 Prediction:
If mitigation is delayed, we expect to see a rise in real-world intrusions leveraging this vulnerability, especially against organizations in energy, defense, and smart city operations. In the next 3 months, several APT groups may begin targeting unpatched systems to gain long-term access, using this as a gateway for larger espionage or sabotage campaigns.
