Critical PTZ Camera Vulnerabilities Put Privacy and Security at Risk—Is Your Facility Safe?

Critical PTZ Camera Vulnerabilities Put Privacy and Security at Risk—Is Your Facility Safe?

Recently, two significant zero-day vulnerabilities have been discovered in NDI PTZ (Network Device Interface Pan-Tilt-Zoom) cameras, threatening their widespread use in sensitive environments. The vulnerabilities, identified as CVE-2024-8956 (rated as critical severity, 9.1) and CVE-2024-8957 (high severity, 7.2), affect cameras using VHD PTZ firmware versions below 6.3.40. The manufacturers impacted include PTZOptics, Multicam Systems SAS, and SMTAV Corporation, which often utilize the Hisilicon Hi3516A V600 SoC series.

These vulnerabilities expose high-cost PTZ cameras—found in settings like industrial plants, business conference rooms, healthcare facilities, government buildings, and houses of worship—to potential full control by attackers. This includes unauthorized viewing and manipulation of live video feeds, as well as the risk of camera operations being disabled or recruited into malicious botnets.

PTZOptics issued an update to patch these vulnerabilities on September 17, 2024, but certain end-of-life models like the PT20X-NDI-G2 and PT12X-NDI-G2 remain unpatched. Updates are still pending for other models, such as the PT20X-SE-NDI-G3 and PT30X-SE-NDI-G3, leaving many users potentially at risk.

Key Takeaways

• High-Risk Exposure: Vulnerabilities CVE-2024-8956 and CVE-2024-8957 put critical PTZ cameras at risk of complete takeover by unauthorized parties, allowing them to spy on private activities or disrupt camera operations.
• Affected Models: Devices from manufacturers such as PTZOptics, Multicam Systems SAS, and SMTAV Corporation running outdated firmware are impacted.
• Patch Status: Some models have been patched, but numerous others—including some end-of-life versions—remain vulnerable.
• Risky Environments: These cameras are deployed in sensitive locations like healthcare facilities, government buildings, and manufacturing plants, which intensifies the potential impact of any breaches.
• Botnet Recruitment: Vulnerable cameras could be recruited into botnets, posing wider cybersecurity threats to organizations.

Deep Analysis

The implications of these PTZ camera vulnerabilities are broad, especially considering the environments where these devices are often deployed. Let’s break down the key risks:

1. Unauthorized Access and Privacy Violations

   • Complete Camera Takeover: The critical CVE-2024-8956 vulnerability (severity 9.1) allows attackers to fully control the affected cameras, including viewing feeds, adjusting movement, and zoom. Sensitive areas like courtrooms, healthcare settings, and government facilities could be compromised, leading to severe privacy violations.
   • Privacy Risks: Unauthorized access can expose classified information, sensitive operational data, or private conversations, which could lead to major breaches in confidentiality or enable espionage.

2. Operational Disruption

   • Disabling or Misusing Cameras: Attackers could exploit these vulnerabilities to disable cameras or redirect their focus, creating blind spots in security surveillance or interrupting critical operations, particularly in industrial or manufacturing plants. This could facilitate theft, vandalism, or other crimes.
   • Denial of Service (DoS): Malicious actors may also use these vulnerabilities to cause the cameras to malfunction or go offline, reducing their utility during critical security operations.

3. Botnet Integration and Broader Threats

   • Botnet Recruitment: These vulnerable cameras are attractive targets for botnet recruitment. Attackers could integrate them into a botnet to launch larger distributed denial-of-service (DDoS) attacks or for other malicious actions, leveraging the weak security often found in IoT devices.
   • Threat to Broader Network: If these cameras are connected to broader organizational networks, attackers could potentially use compromised cameras as a stepping stone to infiltrate other systems, escalating the attack across the infrastructure.

4. Financial and Reputational Consequences

   • High-Cost Devices: PTZ cameras represent a significant financial investment. Any damage caused by unauthorized access or forced upgrades to replace vulnerable end-of-life models will come at a substantial cost to affected organizations.
   • Damage to Public Trust: Organizations handling sensitive footage—such as government bodies or healthcare facilities—could face severe reputational damage if unauthorized video access or operational disruptions become public. Such breaches could erode trust and lead to legal liabilities.

Recommended Actions

Given the severity of these vulnerabilities, organizations using affected cameras should immediately take the following actions to secure their infrastructure:

1. Update Firmware: Apply the latest firmware updates provided by PTZOptics, and stay vigilant for any additional patch releases or security advisories. Make sure that all available patches are installed promptly.
2. Network Segmentation: Ensure that the cameras are placed on segmented networks. Keeping these devices isolated from critical systems will reduce the risk of the vulnerability spreading or attackers accessing other sensitive assets.
3. Proactive Monitoring: Monitor device activity closely. Unusual network traffic, unauthorized access attempts, or unexpected behavior may indicate a compromise.
4. Replace End-of-Life Devices: Since certain models will not receive patches, it’s advisable to consider replacing these units with newer models that have built-in security features and are supported by active firmware updates.

Did You Know?

• The Hisilicon Hi3516A V600 SoC: The System on Chip (SoC) used in these cameras is a widely deployed hardware component for network cameras, known for its integration of high-definition video processing capabilities.
• Botnet Recruitment: According to industry reports, a growing number of IoT devices like these cameras are being targeted for recruitment into botnets because of outdated firmware and weak security protocols. Devices involved in such networks can be used to launch DDoS attacks affecting millions of other systems globally.
• End-of-Life Dilemma: Many companies continue to use devices that are end-of-life due to high replacement costs, despite the security risks. This makes such legacy hardware a preferred target for attackers looking for the path of least resistance.

The recent discoveries underscore the importance of ongoing vigilance in IoT security, particularly for devices deployed in sensitive environments. Organizations should take immediate actions to secure their infrastructure and mitigate risks, especially when using devices known to have critical vulnerabilities.
