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
An unauthenticated stack-based buffer overflow vulnerability exists in ssvr in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when parsing RTSP Digest authentication fields. A remote attacker may exploit this vulnerability by sending a crafted RTSP request containing overly long authentication data, resulting in memory corruption, denial of service, or potentially arbitrary code execution.

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 · moderate confidence

An unauthenticated stack-based buffer overflow in the ssvr component of GeoVision GV-LPC2011 and GV-LPC2211 IP camera devices (firmware V1.12 and earlier) allows remote attackers to corrupt stack memory via oversized RTSP Digest authentication fields due to missing bounds checks.

MitigationUpgrade firmware to V1.13 or later if available; otherwise segment affected devices on isolated VLANs, restrict RTSP access to trusted IPs, and monitor for anomalous RTSP traffic.

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
    Log into the camera's web admin interface and locate the model number on the Device Information or Status page, or inspect the physical label.
    Affected if The device is not a GeoVision GV-LPC2011 or GV-LPC2211.
  2. Determine firmware version
    In the same admin UI, find the firmware version field (usually labeled 'Firmware Version' or 'Version').
    Affected if Firmware version is V1.12 or earlier (including V1.12, V1.11, etc.).
  3. Confirm RTSP service is enabled
    Go to the Network or Streaming settings page and verify that the RTSP server (the ssvr component) is turned on.
    Affected if RTSP is enabled; the vulnerability only applies when the ssvr component is active.
  4. Verify RTSP is reachable from untrusted network
    Scan the device's RTSP port (commonly 554) or check firewall rules to see if the service is exposed to networks other than a trusted VLAN.
    Affected if The RTSP port is open to the internet or to untrusted IP ranges, meaning remote exploitation is possible.

If the device is a GV-LPC2011/LPC2211 running firmware V1.12 or earlier and the RTSP (ssvr) service is enabled and reachable, the environment is affected.

Mitigation

Upgrade firmware to V1.13 or later if available; otherwise segment affected devices on isolated VLANs, restrict RTSP access to trusted IPs, and monitor for anomalous RTSP traffic.
