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
VCM5010 with software versions earlier before V100R002C50SPC100 has an authentication bypass vulnerability. This is due to improper implementation of authentication for accessing web pages. An unauthenticated attacker could bypass the authentication by sending a crafted HTTP request. 5010 with software versions earlier before V100R002C50SPC100 has an arbitrary file upload vulnerability. The software does not validate the files that uploaded. An authenticated attacker could upload arbitrary files to the system.

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

The VCM5010 video management system has two critical vulnerabilities in versions before V100R002C50SPC100: an authentication bypass allowing unauthenticated attackers to access protected web pages via crafted HTTP requests, and an arbitrary file upload flaw enabling authenticated users to upload any file type without validation.

MitigationUpgrade to V100R002C50SPC100 or later. Until then, restrict network access to the VCM5010 management interface and monitor for unauthorized access attempts.

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 VCM5010 firmware version
    Access the VCM5010 management console or check the system information page to determine the currently installed firmware version. Compare it against V100R002C50SPC100.
    Affected if The installed firmware version is any version before V100R002C50SPC100 (for example, V100R002C50SPC050 or earlier).
  2. Confirm web management interface accessibility
    Determine whether the VCM5010 web management interface is reachable from network segments that are not trusted or are external. Check firewall rules or network access control lists restricting access to port 80/443 or the custom HTTP/HTTPS ports used by VCM5010.
    Affected if The web management interface is exposed to untrusted networks without proper access restrictions.
  3. Test for authentication bypass
    Send a crafted HTTP request to a protected page (such as /admin or /config) without providing valid authentication credentials. Observe whether the system grants access to the protected resource.
    Affected if The system returns protected content or allows access without requiring valid authentication.
  4. Verify file upload restrictions
    If you have valid credentials, attempt to upload a file with an extension that should be blocked (such as .exe, .php, or .sh) through the file upload feature. Check whether the system performs any validation on the file type before accepting the upload.
    Affected if The system accepts and stores files without validating the file type or extensions, allowing potentially malicious file types.

A user is affected if the VCM5010 firmware version is before V100R002C50SPC100 and the management interface is network-accessible, since both the authentication bypass and unrestricted file upload vulnerabilities apply.

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

Upgrade to V100R002C50SPC100 or later. Until then, restrict network access to the VCM5010 management interface and monitor for unauthorized access attempts.

Recommended fix High confidence

V100R002C50SPC100

  1. Obtain the firmware version V100R002C50SPC100 or later from the official Huawei support website (support.huawei.com)
  2. Log into the VCM5010 device management console with administrator credentials
  3. Navigate to the System Settings or Administration section of the web interface
  4. Locate the Firmware Upgrade or Software Update option
  5. Upload the V100R002C50SPC100 firmware file and initiate the upgrade process
  6. Wait for the firmware upload and installation to complete - do not power off the device during this process
  7. Restart the VCM5010 device if prompted or required after the upgrade
  8. Verify the firmware version has been updated to V100R002C50SPC100 or later by checking the system information page
