Description
This security bulletin contains information about 1 vulnerability.
1) Authentication bypass (CVE-ID: CVE-2018-19023)
CWE-ID: CWE-294 - Authentication Bypass by Capture-replay
CVSSv4: 7 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:A/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows an adjacent attacker to bypass authentication.
The weakness exists due to use of fixed codes that are reproducible by sniffing and re-transmission. An adjacent attacker can bypass authentication that may lead to replay of a command, spoofing of an arbitrary message, or keeping the controlled load in a permanent “stop” state.
