CVE-2023-0029Network attack vector

Unauthenticated service interruption via undisclosed Telnet processing

Published Jan 1, 2023 · Updated Aug 2, 2024

Denial of service in the Multilaser RE708 Telnet service on firmware RE1200R4GC-2T2R-V3_v3411b_MUL029B allows remote attackers to interrupt service. The CNA record identifies only unknown processing in the Telnet service and does not disclose the input, request, function, or resource mishandled. Network reachability to the Telnet service is sufficient; no authentication or user interaction is required, and the reported consequence is service interruption only.
