CVE-2020-9098
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 OceanStor 5310 product with version of V500R007C60SPC100 has an invalid pointer access vulnerability. The software system access an invalid pointer when attacker malformed packet. Due to the insufficient validation of some parameter, successful exploit could cause device reboot.
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 confidenceHuawei OceanStor 5310 V500R007C60SPC100 contains an invalid pointer access vulnerability where malformed packets trigger access to an invalid pointer due to insufficient validation of certain parameters. Successful exploitation causes device reboot, resulting in 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 OceanStor 5310 modelLog into the device management interface or check the product nameplate/label. From CLI, use: `show product` or `display device information`Affected if The device model is Huawei OceanStor 5310
-
Check firmware versionFrom the device CLI, run: `show version` or `display firmware version`. Compare the displayed firmware version to v500r007c60spc100Affected if Firmware version equals v500r007c60spc100 exactly
-
Verify management interface exposureCheck network configuration by running `show ip interface` or `display management-port configuration` from the CLI. Determine if the management port is reachable from networks outside your administrative controlAffected if Management interface has an IP address accessible from untrusted or external networks
-
Assess network accessibility of devicePing the management IP address from external networks or review firewall rules to determine if malformed packets can reach the deviceAffected if Device management interface is reachable from networks where untrusted parties could send malformed packets
A user is affected if they are running exactly firmware v500r007c60spc100 on an OceanStor 5310 and the management interface is exposed to networks where attackers can send malformed packets.

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 the vendor-provided security patch or firmware update from Huawei. As an interim measure, restrict network access to the management interface and filter malformed packets at the network perimeter to reduce exposure.
