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 · unedited
Huawei SMC2.0 with software of V100R003C10, V100R005C00SPC100, V100R005C00SPC101B001T, V100R005C00SPC102, V100R005C00SPC103, V100R005C00SPC200, V100R005C00SPC201T, V500R002C00, V600R006C00 has an input validation vulnerability when handle TLS and DTLS handshake with certificate. Due to the insufficient validation of received PKI certificates, remote attackers could exploit this vulnerability to crash the TLS module.

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 confidence

Huawei SMC2.0 contains an input validation flaw in its TLS/DTLS handshake certificate processing. The software fails to properly validate received PKI certificates, allowing remote attackers to send specially crafted certificates that crash the TLS module, causing denial of service.

MitigationApply the vendor-provided patches for the affected SMC2.0 versions (V100R003C10 through V600R006C00). If patches are unavailable, consider network-level filtering of untrusted TLS connections or disabling TLS/DTLS services if not operationally critical.

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 the SMC2.0 firmware version
    Access the SMC2.0 management console or check the system information page to view the installed firmware version. This is typically found under 'System' > 'About' or via CLI command 'display version'.
    Affected if The installed version matches any of: v100r003c10, v100r005c00spc100, v100r005c00spc101b001t, v100r005c00spc102, v100r005c00spc103, v100r005c00spc200, v100r005c00spc201t, v500r002c00, or v600r006c00
  2. Verify TLS/DTLS service is enabled
    Check the SMC2.0 configuration for TLS or DTLS protocol settings. Look under 'Security' > 'Certificate Management' or 'Network' > 'TLS Settings' in the management interface. Alternatively, check configuration files for tls-enabled or dtls-enabled parameters.
    Affected if TLS or DTLS services are enabled and configured for use
  3. Confirm network exposure to TLS/DTLS traffic
    Review firewall rules and network access controls to determine if the SMC2.0 TLS/DTLS ports (typically port 443 or custom DTLS ports) are exposed to untrusted networks or the internet. Check inbound access control lists.
    Affected if The TLS/DTLS interfaces are reachable from untrusted networks or the internet

You are affected if your SMC2.0 firmware version exactly matches one of the nine listed versions AND TLS/DTLS services are enabled and exposed to network traffic.

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 data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the vendor-provided patches for the affected SMC2.0 versions (V100R003C10 through V600R006C00). If patches are unavailable, consider network-level filtering of untrusted TLS connections or disabling TLS/DTLS services if not operationally critical.
