Analysis Summary

CVE-2023-38418 CVSS:7.8

F5 BIG-IP (APM) could allow a local authenticated attacker to gain elevated privileges on the system, caused by improper verification of cryptographic signature during the installation process. By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.

CVE-2023-36858 CVSS:7.1

F5 BIG-IP (APM) could allow a local authenticated attacker to bypass security restrictions, caused by an in insufficient verification of data. By sending a specially crafted request, an attacker could exploit this vulnerability to modify configured server list.

CVE-2023-3470 CVSS:6

F5 BIG-IP could allow a local authenticated attacker to obtain sensitive information, caused by a flaw when using Cavium Nitrox FIPS HSM cards to generate passwords. By utilize cryptographic attack techniques, an attacker could exploit this vulnerability to obtain password information for the Crypto User account, and use this information to launch further attacks against the affected system.

CVE-2023-38419 CVSS:4.3

F5 BIG-IP and BIG-IQ Centralized Management is vulnerable to a denial of service. By sending undisclosed requests, a remote authenticated attacker could exploit this vulnerability to cause the iControl SOAP process to terminate.
