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 Missing Authentication in Critical Function in Bosch IP cameras allows an unauthenticated remote attacker to extract sensitive information or change settings of the camera by sending crafted requests to the device. Only devices of the CPP6, CPP7 and CPP7.3 family with firmware 7.70, 7.72, and 7.80 prior to B128 are affected by this vulnerability. Versions 7.62 or lower and INTEOX cameras are not affected.

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

This is a missing authentication vulnerability in Bosch IP cameras (CPP6, CPP7, CPP7.3 families) running firmware versions 7.70, 7.72, and 7.80 prior to B128. An unauthenticated remote attacker can send crafted HTTP requests to the camera to extract sensitive information or modify device settings without any credentials.

MitigationApply vendor-supplied firmware update B128 or later to all affected camera devices. Identify all impacted devices on the network and prioritize patching based on exposure to untrusted networks.

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 the Bosch camera model
    Access the camera web interface, check ONVIF device information, or use SNMP to query the device model. Look for CPP6, CPP7, or CPP7.3 in the model identifier.
    Affected if The device model is a Bosch CPP6, CPP7, or CPP7.3 camera family
  2. Retrieve the firmware version
    In the camera web interface, navigate to the System Overview or Maintenance page to view the firmware version. Alternatively, query via ONVIF GetDeviceInformation or SNMP OID for firmware version.
    Affected if The installed firmware version cannot be determined or is not visible through standard interfaces
  3. Compare firmware against affected versions
    Check if the installed version matches: 7.70, 7.72, or any 7.80.x version below 7.80.0129. Note that versions 7.80.0129 and later, and versions below 7.70, are NOT affected.
    Affected if The firmware version is exactly 7.70, 7.72, or falls in the range 7.80.0000 through 7.80.0128
  4. Verify network exposure (context)
    Determine if the camera HTTP interface is accessible from untrusted networks. Check firewall rules, VLAN segmentation, and access control lists restricting camera management ports.
    Affected if The camera HTTP interface is directly exposed to untrusted networks without authentication barriers

A user is affected if they have a Bosch CPP6, CPP7, or CPP7.3 camera running firmware version 7.70, 7.72, or 7.80 prior to 7.80.0129, with the HTTP interface accessible on the network.

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.

dbcve · scoped
Upgrade available Upgrade to 7.80.0129 or later
Fixed in 7.80.0129
Interim mitigation

Apply vendor-supplied firmware update B128 or later to all affected camera devices. Identify all impacted devices on the network and prioritize patching based on exposure to untrusted networks.

Recommended fix High confidence

Firmware 7.80.0129 (B128) or later

  1. Identify the specific Bosch IP camera model (CPP6, CPP7, or CPP7.3 family)
  2. Access the camera's web interface or management console
  3. Check the current firmware version under System > Overview or similar
  4. If the firmware is 7.70, 7.72, or 7.80.x prior to B128, download the latest firmware update (7.80.0129 or later/B128 or higher) from the official Bosch download portal
  5. Upload and apply the firmware update via the camera's administration interface
  6. Allow the camera to complete the reboot process
  7. Verify the firmware version has been updated to 7.80.0129 or later
