CVE-2017-17164
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 · uneditedHuawei Secospace AntiDDoS8000 V500R001C20SPC500 have a memory leak vulnerability due to memory don't be released when the system open some function. An attacker could exploit it to cause memory leak, which may further lead to system exceptions.
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 confidenceA memory leak vulnerability exists in Huawei Secospace AntiDDoS8000 V500R001C20SPC500 where memory is not properly released when certain system functions are opened. An unauthenticated remote attacker could trigger the affected function(s) to cause progressive memory exhaustion, eventually leading to system exceptions and potential denial of service.

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.
-
Confirm product identityAccess the device CLI or web interface and verify the device model is Huawei Secospace AntiDDoS8000. This can typically be done via 'display device information' command in CLI or checking the system status page in web interface.Affected if Device model is Huawei Secospace AntiDDoS8000 and firmware version equals v500r001c20spc500 exactly
-
Verify firmware versionCheck the installed firmware version via 'display version' command in CLI or through the web interface system management section. Confirm the version string matches exactly: V500R001C20SPC500Affected if Firmware version is exactly V500R001C20SPC500 (no other versions are affected per the advisory)
-
Check management interface exposureReview network configuration to determine if the device management interface (typically ports 443, 80, or 22) is accessible from untrusted networks. Use 'display ip interface' or review firewall policies to list exposed management IPs.Affected if Management interface is reachable from unauthenticated remote network sources (attacker requires network access to trigger the affected functions)
-
Review accessible system functionsIdentify which system functions or features are enabled and accessible. Check service configurations via 'display service' or 'display current-configuration' commands to enumerate exposed functions.Affected if Any system function that can be triggered by an unauthenticated remote attacker is enabled and accessible
-
Monitor for memory anomaliesCollect baseline memory usage via 'display memory' command or through SNMP monitoring. Track memory consumption over time, particularly watching for progressive growth that does not return to baseline.Affected if Memory usage shows continuous growth without recovery, indicating active exploitation of the memory leak
You are affected if your device is Huawei Secospace AntiDDoS8000 running exactly firmware version V500R001C20SPC500 and the management interface is network-accessible to trigger the vulnerable system functions.

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-provided patches for V500R001C20SPC500. As a compensating control, limit network access to the management interface and monitor system memory usage for anomalous growth patterns indicating active exploitation.
