Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU31723
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-3357
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input in the Secure Sockets Layer (SSL) VPN feature. A remote attacker can send a specially crafted HTTP request and execute arbitrary code on the target device or cause the device to reload, resulting in a denial of service (DoS) condition.
MitigationInstall updates from vendor's website.
