D-Link has reported multiple unpatched security vulnerabilities in its DGS-3130 series managed switches, discovered by engineer Giresh Kumar Enugu. These flaws affect the D-Link Discovery Protocol (DDP) and could allow attackers to access sensitive device data, make unauthorized changes, or disrupt services. The vulnerabilities impact several firmware versions of the DGS-3130-30TS model, with ongoing investigations into other D-Link platforms. D-Link has not assigned CVE identifiers for these vulnerabilities yet. Until patches are available, the company recommends disabling DDP, removing default SNMP strings, and restricting access to management interfaces. This follows a previous warning about a zero-day affecting legacy DIR-822A routers in September 2026. Administrators are advised to maintain offline backups and monitor logs for unusual activity.
