These flaws, which include missing authentication for critical functions, improper token management, and lack of authentication rate limiting, expose the device to full compromise by unauthenticated remote attackers. An adversary can exploit these weaknesses to access sensitive configuration data, modify system settings, or cause a denial-of-service condition. Because the web management interface does not consistently verify origin or privilege levels, an attacker can effectively bypass security controls to gain administrative access. The vendor has acknowledged these findings but has not released security patches to address these issues. Organizations deploying these devices globally in the Information Technology sector should take immediate steps to isolate affected hardware from the public internet.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker identifies an internet-facing Ebyte NA111-M device via network scanning.\u003c/li\u003e\n\u003cli\u003eThe attacker targets the web management interface using CVE-2026-73125 to gain unauthenticated access to device settings.\u003c/li\u003e\n\u003cli\u003eAlternatively, the attacker uses CSRF (CVE-2026-75814) by tricking an administrator into interacting with a malicious link to trigger unauthorized configuration changes.\u003c/li\u003e\n\u003cli\u003eThe attacker performs brute-force or credential-stuffing attacks against the management portal, aided by the lack of rate limiting (CVE-2026-76940).\u003c/li\u003e\n\u003cli\u003eThe attacker intercepts or steals session tokens due to improper client-side protection (CVE-2026-76179) to impersonate legitimate administrative sessions.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages the lack of function separation (CVE-2026-77966) to escalate from a low-privileged user to full administrative rights.\u003c/li\u003e\n\u003cli\u003eFinal objectives include device exfiltration of sensitive configuration data or complete disruption of service.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation results in full administrative control over the Ebyte NA111-M device.
