Attacker can exploit it to make one process reboot at random.

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 an overflow vulnerability in the SIP (Session Initiation Protocol) module of multiple Huawei video conferencing and unified communication devices. The vulnerability exists in the module's validation of variables when parsing malformed SIP messages, allowing an unauthenticated remote attacker to send specially crafted SIP packets that cause a process to reboot, resulting in denial of service.

MitigationApply vendor-supplied firmware patches for the affected versions; if patches are unavailable, consider network segmentation to limit SIP exposure and implement firewall rules to restrict SIP traffic to trusted sources.

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 administration interface or use the command line interface (CLI) to query the system version. For Huawei video conferencing devices, this is typically done via 'display version' or through the web management interface under 'System Information' or 'Device Status'.
    Affected if The device model is one of: Dp300, Rp200, Rse6500, Te30, Te40, Te50, Te60, or Tp3106 AND the firmware version matches any of the specific versions listed in the CVE (e.g., v500r002c00, v600r006c00, v100r001c10spc300, etc.).
  2. Confirm SIP module is enabled
    Log into the device CLI or web interface and navigate to the SIP configuration settings. Check the SIP service status under 'SIP' or 'Protocol' settings in the conferencing or network configuration menu. Alternatively, check running processes via 'display process' or review the device's active service list.
    Affected if The SIP protocol module or service is actively enabled on the device. The vulnerability only affects systems where SIP processing is turned on.
  3. Check network exposure to SIP traffic
    Review firewall rules, access control lists (ACLs), or network segmentation configurations to determine if the device's SIP port (typically UDP/TCP 5060) is exposed to untrusted networks or the public internet. Use 'display firewall policy' or review the security zone configuration.
    Affected if The device can receive SIP packets from untrusted or external network sources. An attacker must be able to send malicious SIP packets to the device for the vulnerability to be exploitable.

A user is affected if they have one of the listed Huawei device models running one of the specific firmware versions listed, with the SIP module enabled and accessible from a network where an attacker could send malformed SIP packets.
