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
The Cisco Video Surveillance IP Gateway Encoder/Decoder (Standalone and Module) firmware 1.8.1 and earlier, Video Surveillance SP/ISP Decoder Software firmware 1.11.0 and earlier, and the Video Surveillance SP/ISP firmware 1.23.7 and earlier have default passwords for the sypixx and root user accounts, which allows remote attackers to perform administrative actions, aka CSCsj34681.

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

Cisco Video Surveillance IP Gateway Encoder/Decoder devices and SP/ISP Decoder Software ship with hardcoded default passwords for 'sypixx' and 'root' user accounts. Remote attackers can authenticate with these credentials to gain full administrative access to the surveillance equipment, allowing configuration changes, video stream interception, or network pivoting.

MitigationImmediately change default passwords on all affected Cisco Video Surveillance devices to strong, unique credentials. Consider firmware updates to latest versions if available, and implement network segmentation to limit exposure of video surveillance infrastructure.

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 device model and firmware version
    Access the device web interface or use SNMP to retrieve the system firmware version. Typically found under System or Administration > Device Info in the web UI, or via SNMP OID sysDescr.
    Affected if Firmware version is 1.8.1 or lower for IP Gateway Encoder/Decoder, 1.11.0 or lower for SP/ISP Decoder Software, or 1.23.7 or lower for SP/ISP.
  2. Verify default sypixx account status
    Attempt to authenticate to the device management interface (web or telnet) using the username 'sypixx' with its default password. The default password for sypixx was publicly documented in the vulnerability disclosure.
    Affected if Authentication succeeds with sypixx/default password combination, indicating the default credential is still active.
  3. Verify default root account status
    Attempt to authenticate to the device management interface (web, telnet, or SSH) using the username 'root' with its default password. The default root password was publicly documented in the vulnerability disclosure.
    Affected if Authentication succeeds with root/default password combination, indicating the default credential is still active.
  4. Check remote access configuration
    Review the device network settings to determine if remote management interfaces (web UI, telnet, SSH) are exposed to untrusted networks. Check ACLs, firewall rules, and interface bindings.
    Affected if Remote management interfaces are accessible from untrusted networks (such as the internet or dmz) without additional authentication barriers.

The environment is affected if the device runs an affected firmware version AND retains either the sypixx or root default credentials AND has remote management access exposed.
