Buffer overflow in the Point-to-Point Protocol over Ethernet (PPPoE) module in Huawei USG2100, USG2200, USG5100, and USG5500 unified security gateways with software before V300R001C10SPC600, when CHAP authentication is configured on the server, allows remote attackers to cause a denial of service (server restart) or execute arbitrary code via crafted packets sent during authentication.

Security readout for executives and security teams

This CVE affects specific Huawei USG security gateways using PPPoE server CHAP authentication. Malformed authentication traffic can overflow memory, potentially restarting the device or allowing code execution. Business risk is highest where these legacy gateways still terminate PPPoE sessions. Exposure appears limited to listed Huawei USG gateway models running affected software and configured as a PPPoE server with CHAP authentication. The source bundle does not identify other products, default exposure, or internet prevalence. Prioritize if these Huawei USG gateways are still deployed for PPPoE access. The issue can disrupt perimeter services and may allow code execution, but urgency depends on confirmed model, version, and CHAP server configuration. Mitigation focus: Inventory Huawei USG2100, USG2200, USG5100, and USG5500 devices.; Confirm software is V300R001C10SPC600 or later.; Review Huawei PSIRT guidance before changing production gateways..
