CVE-2017-15319
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 · uneditedRP200 V500R002C00, V600R006C00; TE30 V100R001C10, V500R002C00, V600R006C00; TE40 V500R002C00, V600R006C00; TE50 V500R002C00, V600R006C00; TE60 V100R001C10, V500R002C00, V600R006C00 have an out-of-bounds read vulnerabilities in some Huawei products. Due to insufficient input validation, a remote attacker could exploit these vulnerabilities by sending specially crafted SS7 related packets to the target devices. Successful exploit will cause out-of-bounds read and possibly crash the system.
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 confidenceThis vulnerability exists in SS7 protocol parsing within multiple Huawei video conferencing endpoints (RP200, TE30-TE60). Insufficient input validation when processing specially crafted SS7 packets allows a remote attacker to read memory beyond buffer boundaries, potentially exposing sensitive information and causing system crashes.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify device model and firmware versionAccess the device web interface, CLI console, or system information page. Look for the model number (RP200, TE30, TE40, TE50, or TE60) and firmware version string.Affected if The device is one of RP200, TE30, TE40, TE50, or TE60 AND the firmware version is exactly v100r001c10, v500r002c00, or v600r006c00
-
Check SS7 protocol configurationNavigate to device network settings, protocol configuration, or telephony/SS7 settings in the web interface or CLI. Look for SS7 protocol enable/disable status.Affected if SS7 protocol parsing or handling is enabled on the device
-
Verify network exposure to SS7 trafficReview firewall rules, access control lists, and network segmentation policies surrounding the video conferencing endpoint. Determine if the device can receive SS7 packets from untrusted network sources.Affected if The device has open network access to untrusted SS7 traffic sources without proper filtering or segmentation
A user is affected if they are running one of the listed firmware versions on RP200, TE30, TE40, TE50, or TE60 devices with SS7 protocol enabled and accessible to untrusted network sources.

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.
From vendor dataApply vendor-supplied patches/firmware updates for the specific product versions listed. If patches are unavailable, consider network segmentation to limit exposure to untrusted SS7 traffic sources.
