CVE-2025-39240
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSome Hikvision Wireless Access Point are vulnerable to authenticated remote command execution due to insufficient input validation. Attackers with valid credentials can exploit this flaw by sending crafted packets containing malicious commands to affected devices, leading to arbitrary command execution.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is an authenticated command injection vulnerability in Hikvision Wireless Access Points. Attackers with valid device credentials can send specially crafted packets containing malicious commands that bypass input validation, leading to arbitrary command execution on the affected device with the privileges of the web service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Hikvision Wireless Access Point in your networkCheck device inventory or perform network discovery to locate Hikvision access points. Look for devices with Hikvision branding or MAC OUI, and verify the model number through the web interface or SNMP.Affected if The device is a Hikvision Wireless Access Point and is network-accessible.
-
Check firmware versionLog into the device web management interface and navigate to the System or Status page to view the firmware version. Alternatively, use SNMP or the Hikvision SADP tool to retrieve version information.Affected if The installed firmware version falls within the affected range (compare your version to official Hikvision security advisories for CVE-2025-39240).
-
Verify web management interface accessibilityConfirm that the device HTTP/HTTPS management interface is reachable from network segments. Check firewall rules and device network settings to determine exposure.Affected if The web management interface is accessible from untrusted or external network segments.
-
Review authentication configurationCheck if default credentials are in use, weak passwords are configured, or if the device allows authentication from multiple concurrent sessions. Review user accounts in the device management interface.Affected if Default credentials remain unchanged, weak passwords are used, or multiple simultaneous admin sessions are allowed.
-
Check for indicators of compromiseReview device logs for unusual authentication events, unexpected command executions, or unknown processes. Monitor network traffic for suspicious POST requests to the management interface with unusual payload patterns.Affected if Logs show unauthorized command execution, unexpected admin activity, or anomalous management traffic.
Your environment is affected if you have a Hikvision Wireless Access Point with a vulnerable firmware version that has its web management interface accessible to attackers who could obtain valid credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict access to trusted administrators only using strong, unique credentials and network segmentation. Monitor for suspicious authentication activity and check with Hikvision for available firmware patches.
