CVE-2026-61392 Overview
CVE-2026-61392 is an information disclosure vulnerability affecting select Hikvision camera models. Unauthenticated attackers can retrieve partial contents of the device's memory over the network. The flaw is categorized under [CWE-200] Exposure of Sensitive Information to an Unauthorized Actor. Because the attack requires no authentication and no user interaction, exploitation is straightforward for any actor with network access to the camera's management interface. Leaked memory contents may include session artifacts, configuration fragments, or other transient runtime data useful for follow-on attacks against surveillance infrastructure.
Critical Impact
Unauthenticated network attackers can read fragments of device memory from affected Hikvision cameras, potentially exposing sensitive runtime data.
Affected Products
- Hikvision cameras (specific models identified in the vendor advisory)
- Refer to the Hikvision Security Advisory for the impacted firmware list
- Downstream OEM camera products built on affected Hikvision firmware

Technical Details for CVE-2026-61392
Vulnerability Analysis
The vulnerability allows an unauthenticated remote attacker to obtain partial information from the memory of affected Hikvision cameras. The confidentiality impact is limited to fragments rather than full memory disclosure, but no privileges or user interaction are needed to trigger the disclosure. Integrity and availability of the device are not directly affected. Attackers commonly chain memory disclosure flaws with other weaknesses to defeat address space layout randomization, harvest credentials from buffers, or fingerprint firmware versions for targeted follow-up exploitation.
Root Cause
The issue is classified as [CWE-200] Exposure of Sensitive Information to an Unauthorized Actor. A network-facing service on the camera returns data that includes uninitialized or out-of-scope memory regions in its response. Hikvision has not published the specific service, request handler, or firmware component in the public advisory summary. Consult the Hikvision Security Advisory for the authoritative technical writeup.
Attack Vector
Exploitation occurs over the network against the camera's exposed management or media interface. The attacker sends a crafted request to the vulnerable service, and the response includes bytes drawn from adjacent memory. Repeated requests can be issued to accumulate additional memory fragments. See the vendor advisory for technical specifics rather than synthetic proof-of-concept code.
Detection Methods for CVE-2026-61392
Indicators of Compromise
- Unusual volume of requests from external addresses to camera HTTP, RTSP, or SDK service ports
- Response traffic to unauthenticated endpoints exceeding expected payload sizes
- Access to Hikvision management endpoints from source addresses outside normal management subnets
Detection Strategies
- Inspect network telemetry for repeated unauthenticated probes against camera management interfaces
- Correlate camera firmware versions against the affected list published in the Hikvision advisory
- Monitor for anomalous outbound flows from cameras that could indicate post-disclosure follow-on activity
Monitoring Recommendations
- Ingest camera and network device logs into a centralized SIEM for baselined behavior analysis
- Alert on any direct exposure of Hikvision cameras to the public internet via periodic external attack surface scans
- Track authentication failure and connection patterns against surveillance VLANs
How to Mitigate CVE-2026-61392
Immediate Actions Required
- Enumerate all Hikvision cameras and firmware versions in the environment and match them against the vendor advisory
- Apply the firmware update supplied by Hikvision as soon as it is available for the identified models
- Restrict access to camera management interfaces to trusted management networks only
- Rotate any credentials or keys that could have been exposed on affected devices
Patch Information
Hikvision has published firmware updates addressing this vulnerability. Refer to the Hikvision Security Advisory for the model-specific firmware versions and download instructions.
Workarounds
- Place cameras on isolated VLANs with no direct inbound access from the internet or general user networks
- Enforce ACLs on network switches and firewalls to permit management traffic only from designated admin hosts
- Disable unused network services on the camera to reduce exposed attack surface
- Front camera services with a reverse proxy or VPN gateway that requires authentication before reaching the device
