Summary

CVE-2026-57600 is a high-severity information disclosure vulnerability affecting Hikvision DS-2CD, DS-2DE, DS-2DP, and DS-2TD Series IP cameras. Insufficient validation of input parameters in the device firmware allows unauthenticated remote attackers to retrieve partial sensitive data from affected devices over the network. Discovered by the Bitdefender IoT Security Team, the vulnerability carries a CVSS v3.1 base score of 7.5 (High).

Technical details

  • Root cause: Insufficient validation of input parameters in the firmware’s network-facing interface, enabling malformed or crafted requests to bypass expected processing boundaries and return sensitive data.
  • Trigger conditions: No authentication, no user interaction, and no special configuration required. The attack can be carried out by any network-reachable attacker against an internet-exposed device.
  • Attack vector: Network-based (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N).
  • Impact: Unauthenticated retrieval of partial sensitive data from affected camera firmware. The CVSS Confidentiality impact is rated High (C:H), indicating significant sensitive information is accessible to an attacker. Integrity and availability are not affected (I:N/A:N).

Affected software

  • Hikvision DS-2CD Series IP cameras (affected firmware versions)
  • Hikvision DS-2DE Series IP cameras (affected firmware versions)
  • Hikvision DS-2DP Series IP cameras (affected firmware versions)
  • Hikvision DS-2TD Series IP cameras (affected firmware versions)

Specific affected firmware version ranges and corresponding fixed firmware versions are detailed in Hikvision’s official security advisory (see References).

Severity

  • CVSS v3.1 Base Score: 7.5 (High)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Mitigation and recommended actions

  • Immediate: Apply the firmware update for affected device models provided by Hikvision. Consult the official Hikvision security advisory (linked in References) for the specific patched firmware versions applicable to each model.
  • Network mitigation: If immediate firmware patching is not possible, restrict internet-facing access to camera web interfaces by placing affected devices behind a firewall or VPN, preventing unauthenticated access from untrusted networks.
  • Audit exposure: Identify all internet-exposed Hikvision DS-2CD, DS-2DE, DS-2DP, and DS-2TD Series cameras in your environment and prioritize remediation for any devices directly reachable from the public internet.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
