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
A cleartext password storage issue was discovered on MicroDigital N-series cameras with firmware through 6400.0.8.5. The file in question is /usr/local/ipsca/mipsca.db. If a camera is compromised, the attacker can gain access to passwords and abuse them to compromise further systems.

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

MicroDigital N-series cameras with firmware through 6400.0.8.5 store user credentials in cleartext within the database file /usr/local/ipsca/mipsca.db. An attacker who compromises the device can directly read this file to obtain plaintext passwords, enabling lateral movement to other systems using those credentials.

MitigationApply vendor firmware patch when available; if patch is unavailable, implement network segmentation to isolate cameras, rotate all compromised credentials, and monitor for unauthorized access using the exposed credentials.

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 camera model
    Log into the camera web interface or check the device label to confirm the exact model (Mdc N4090, Mdc N4090w, or Mdc N2190v)
    Affected if Model is Mdc N4090, Mdc N4090w, or Mdc N2190v
  2. Check firmware version
    Access the camera's web interface under System > Info or use the ONVIF/SNMP interface to retrieve the firmware version number
    Affected if Firmware version is 6400.0.8.5 or lower
  3. Locate the database file
    Access the device via SSH or UART and attempt to read /usr/local/ipsca/mipsca.db (requires root or limited shell access)
    Affected if The file /usr/local/ipsca/mipsca.db exists on the device
  4. Verify cleartext credentials
    Open the mipsca.db file using sqlite3 or a hex editor and search for user account entries to confirm passwords are stored in plaintext rather than hashed
    Affected if User credentials in the database appear as plaintext passwords

A user is affected if they have a MicroDigital Mdc N4090, N4090w, or N2190v camera running firmware version 6400.0.8.5 or lower, and the /usr/local/ipsca/mipsca.db file contains plaintext passwords.

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 data
Upgrade available Upgrade to a release after 6400.0.8.5
Interim mitigation

Apply vendor firmware patch when available; if patch is unavailable, implement network segmentation to isolate cameras, rotate all compromised credentials, and monitor for unauthorized access using the exposed credentials.
