Description
This security bulletin contains information about 1 vulnerability.
1) Authentication bypass (CVE-ID: CVE-2017-3765)
CWE-ID: CWE-592 - Authentication Bypass Issues
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to bypass security restrictions on the target system.
The weakness exists in the Enterprise Network Operating System (ENOS) firmware due to the presence of a mechanism, known as HP Backdoor, for bypassing authentication on the affected switches. A local attacker can use credentials unique to a targeted switch to authenticate to the switch, bypass authentication and gain administrative-level access to the switch.
Successful exploitation of the vulnerability may result in system compromise.
