1) Session Fixation
EUVDB-ID: #VU18691
Risk: High
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2019-9744
CWE-ID:
CWE-384 - Session Fixation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain unauthorized access to the web interface.
The vulnerability exists due to improper access restrictions when attackers arriving from the same source IP address as an authenticated user, because this IP address is used as a session identifier. A remote unauthorized attacker can get access to the web interface, which may allow full access to the device configuration.
Mitigation- operate the devices in closed networks or protected with a suitable firewall
- Log off from the WEB-UI immediately after administration.
- Disable the WEB-UI and use configuration access via SNMP instead.
- Ensure the system password is strong as this is also the SNMP write community.
