CVE-2023-22374 : Exploit Details and Defense Strategies

This CVE-2023-22374 article provides detailed information about a vulnerability in iControl SOAP discovered in F5's BIG-IP affected versions.

Understanding CVE-2023-22374

This section delves into the vulnerability, its impact, technical details, and mitigation strategies.

What is CVE-2023-22374?

A format string vulnerability in iControl SOAP allows an authenticated attacker to crash the iControl SOAP CGI process or potentially execute arbitrary code. In appliance mode BIG-IP, exploiting this vulnerability can enable the attacker to cross a security boundary. It is important to note that software versions at End of Technical Support (EoTS) are not evaluated for this issue.

The Impact of CVE-2023-22374

The vulnerability has a high severity level with a CVSS base score of 7.5/8.5, presenting a high risk in terms of confidentiality, integrity, and availability. The attack complexity is high, with low privileges required, and the attack vector is through the network. For general scenarios and in appliance mode, the impact can lead to unauthorized access and code execution.
