CVE-2020-1827
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 NIP6800 versions V500R001C30, V500R001C60SPC500, and V500R005C00SPC100; and Secospace USG6600 and USG9500 versions V500R001C30SPC200, V500R001C30SPC600, V500R001C60SPC500, and V500R005C00SPC100 have an information leakage vulnerability. An attacker can exploit this vulnerability by sending specific request packets to affected devices. Successful exploit may lead to information leakage.
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 confidenceThis is an information disclosure vulnerability in Huawei NIP6800 and Secospace USG6600/USG9500 security appliances. An unauthenticated attacker can send specific crafted request packets to the affected devices to trigger the leak of sensitive information. The CVSS 7.5 score indicates high-severity impact from the exposed data.

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 the device modelAccess the device CLI or web interface and retrieve the product model name (NIP6800, USG6600, or USG9500). In CLI, use 'display device manuinfo' or check the system information page.Affected if The device model is Huawei NIP6800, Secospace USG6600, or USG9500.
-
Retrieve the firmware versionIn the device CLI, run 'display version' or check the firmware/version information in the web management interface. Note the exact version string such as v500r001c30, v500r001c60spc500, v500r005c00spc100, v500r001c30spc200, or v500r001c30spc600.Affected if The installed firmware version exactly matches one of these: v500r001c30, v500r001c60spc500, v500r005c00spc100, v500r001c30spc200, or v500r001c30spc600.
-
Verify management interface exposureCheck the network configuration to determine if the device management interface (HTTP/HTTPS or SSH on port 23/443) is accessible from untrusted networks. Review the firewall policy or ACLs applied to the device management zone.Affected if The management interface is reachable from the internet or an untrusted network segment without proper access controls.
-
Inspect logs for crafted requestsReview the device security logs, audit logs, or traffic logs for any incoming requests that may contain abnormal or specially crafted packets targeting the vulnerable component. Look for requests that trigger information disclosure.Affected if Logs show unusual or crafted request patterns that precede any sensitive information leakage events.
A user is affected if they are running one of the listed firmware versions (v500r001c30, v500r001c60spc500, v500r005c00spc100, v500r001c30spc200, v500r001c30spc600) on a Huawei NIP6800, USG6600, or USG9500 device with an exposed management interface.
Generated from the published advisory. Verify against your own configuration.
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 or firmware updates to all affected versions (V500R001C30, V500R001C60SPC500, V500R005C00SPC100, V500R001C30SPC200, V500R001C30SPC600). If patches are unavailable, restrict network access to management interfaces and monitor for suspicious request patterns.
