CVE-2026-27521Network attack vector

Account compromise via unrestricted login attempts

Published Feb 24, 2026 · Updated Feb 24, 2026

Login throttling failure in Binardat 10G08-0800GSM 300SP10260209 and earlier allows remote attackers to gain account access by password guessing. The device login mechanism accepts repeated failed authentication attempts without rate limiting or account lockout. Network access to a management interface is sufficient, and a successful guess grants the privileges of the compromised account.
