There is a command injection vulnerability in S12700 V200R019C00SPC500, S2700 V200R019C00SPC500, S5700 V200R019C00SPC500, S6700 V200R019C00SPC500 and S7700 V200R019C00SPC500. A module does not verify specific input sufficiently. Attackers can exploit this vulnerability by sending malicious parameters to inject command. This can compromise normal service.

Security readout for executives and security teams

Plain-English summary

CVE-2021-22377 is a command injection flaw in specific Huawei S-series switch software. If an attacker can reach the vulnerable function and send malicious parameters, normal service could be compromised. The public bundle does not provide CVSS, affected module detail, authentication requirements, or fixed-version information.

Executive priority

Prioritize identification and vendor guidance review for affected network infrastructure. Command injection in switches can affect availability and control, but urgency cannot be precisely ranked from the provided data because severity and exploitation evidence are missing.

Technical view

The CVE describes insufficient validation of specific input in a module affecting S12700, S2700, S5700, S6700, and S7700 running V200R019C00SPC500. Malicious parameters may inject commands. Public data does not identify the interface, prerequisite privileges, exploit path, or remediation version.

Likely exposure

Exposure is limited to organizations operating the listed Huawei switch families on V200R019C00SPC500. Risk is higher where switch management or vulnerable services are reachable from untrusted networks, but the source bundle does not identify the exposed interface.

Exploitation context

No CISA KEV listing is provided, and the source bundle does not cite active exploitation or public exploit availability. Treat exploitability details as incomplete because the affected module and attack preconditions are not disclosed here.

Researcher notes

The public record is sparse: no CVSS, CWE, affected module, attack vector, privilege requirement, or fixed version is present in the bundle. Avoid assuming internet exploitability. Validation should focus on exact model/version matching and management-plane exposure.

Mitigation direction

  • Inventory Huawei S12700, S2700, S5700, S6700, and S7700 switches.
  • Confirm whether any devices run V200R019C00SPC500.
  • Check Huawei PSIRT advisory and support channels for fixed software guidance.
  • Limit switch management access to trusted administration networks.
  • Monitor affected devices for abnormal configuration changes or service disruption.

Validation and detection

  • Match device model and software version against the affected list.
  • Review asset records for Huawei S-series switches in production networks.
  • Verify management-plane exposure from internal, partner, and remote-access networks.
  • Check logs for unexpected administrative actions or service instability.
  • Document any uncertainty around module exposure or authentication requirements.
