Vulnerability from fkie_nvd - Published: 2019-07-19 23:15 - Updated: 2024-11-21 04:51
Severity ?
7.5 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
An issue was discovered on AudioCodes Mediant 500L-MSBR, 500-MBSR, M800B-MSBR and 800C-MSBR devices with firmware versions F7.20A at least to 7.20A.252.062. The (1) management SSH and (2) management TELNET features allow remote attackers to cause a denial of service (connection slot exhaustion) via 5 unauthenticated connection attempts, because the maximum number of unauthenticated clients that can be configured is 5. NOTE: the vendor's position is that this is a "design choice.
