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 · unedited
HiSecOS web server versions 03.4.00 prior to 04.1.00 contains a privilege escalation vulnerability that allows authenticated users with operator or auditor roles to escalate privileges to the administrator role by sending specially crafted packets to the web server. Attackers can exploit this flaw to gain full administrative access to the affected device.

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 · high confidence

HiSecOS web server versions 03.4.00 prior to 04.1.00 contains a privilege escalation vulnerability in its authentication/authorization mechanism. Authenticated users with operator or auditor roles can send specially crafted packets to the web server to elevate their privileges to the administrator role, achieving full administrative access to the affected device.

MitigationUpgrade HiSecOS to version 04.1.00 or later to remediate this vulnerability. Until then, minimize network exposure of the web interface and monitor for suspicious administrative activity.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify HiSecOS web server version
    Access the device management interface or use system information commands (such as 'show system information' or similar device-specific commands) to retrieve the installed HiSecOS version
    Affected if The version is 03.4.00 or any version prior to 04.1.00 (e.g., 03.3.x, 03.2.x, earlier)
  2. Confirm web server is accessible
    Verify that the HiSecOS web interface is enabled and reachable by attempting to access the device IP via HTTP/HTTPS or checking web server status via management commands
    Affected if The web server is running and accessible to network clients
  3. Review configured user accounts and roles
    Examine the device user configuration to identify accounts with operator or auditor roles by using commands like 'show users' or accessing the user management section of the device
    Affected if Any accounts exist with operator or auditor role assignment (these roles can be exploited to gain administrator access)
  4. Check authentication settings
    Verify that local or remote authentication is enabled for the web server by reviewing authentication configuration files or management interface settings
    Affected if User authentication is enabled for the web interface (authentication is a prerequisite for the privilege escalation)
  5. Compare version against affected range
    If version cannot be directly determined, check firmware or software bundle version information and compare numerically to 04.1.00
    Affected if The installed firmware or software version is numerically less than 04.1.00 (e.g., any 03.x.x release)

You are affected if the HiSecOS version is 03.4.00 or any earlier version, the web server is running, and operator or auditor role accounts exist on the system.

Generated from the published advisory. Verify against your own configuration.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade HiSecOS to version 04.1.00 or later to remediate this vulnerability. Until then, minimize network exposure of the web interface and monitor for suspicious administrative activity.

Recommended fix High confidence

HiSecOS version 04.1.00 or later

  1. Identify the HiSecOS version running on the affected device through the web interface or CLI
  2. If the version is 03.4.00 or any version prior to 04.1.00, upgrade the firmware to version 04.1.00 or later
  3. After upgrading, verify the new version is correctly installed by checking the system information
  4. Review user accounts and their assigned roles (operator, auditor, administrator) to confirm no unauthorized privilege escalation occurred prior to the patch
Caveat As with any firmware upgrade, verify compatibility with your specific device model and review release notes for any configuration or feature changes before applying

Generated from the published advisory — verify against the referenced sources before acting.
