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

A buffer overflow vulnerability exists in the SIP module of multiple Huawei video conferencing and IP phone products. Attackers can exploit this by sending a specially crafted SIP message, causing a process reboot and resulting in denial of service.

MitigationApply the vendor-supplied firmware update from Huawei to address the SIP module overflow vulnerability.

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 Huawei product model
    Locate the product model label on the device physical label or access the device admin interface to confirm the model number (Dp300, Rp200, Rse6500, Te30, Te40, Te50, Te60, or Tp3106)
    Affected if The model is one of the affected products listed in the CVE (Dp300, Rp200, Rse6500, Te30, Te40, Te50, Te60, Tp3106)
  2. Check the installed firmware version
    Access the device admin web interface or CLI and navigate to System Status or About page to retrieve the exact firmware version string (for example, v500r002c00spc500)
    Affected if The installed firmware version matches any of the versions listed for that product in the CVE affected versions section
  3. Verify SIP module is enabled
    Access the device admin interface and check the SIP or Telephony settings configuration to determine if the SIP protocol module is currently enabled
    Affected if SIP module is enabled and the firmware version is in the affected list
  4. Check for SIP service exposure
    Review network configuration to determine if the device SIP port (typically port 5060) is exposed to untrusted networks or the internet
    Affected if SIP is enabled and the service is reachable from untrusted network segments

The environment is affected if the device is one of the listed models (Dp300, Rp200, Rse6500, Te30, Te40, Te50, Te60, Tp3106), runs an affected firmware version from the CVE list, and has the SIP module enabled.
