F5 has warned of a high-severity flaw impacting BIG-IP appliances that could lead to denial-of-service (DoS) or arbitrary code execution.

The issue is rooted in the iControl Simple Object Access Protocol (SOAP) interface and affects the following versions of BIG-IP –

  • 13.1.5
  • – 14.1.5
  • – 15.1.8
  • – 16.1.3, and
  • 17.0.0

“A format string vulnerability exists in iControl SOAP that allows an authenticated attacker to crash the iControl SOAP CGI process or, potentially execute arbitrary code,” the company said in an advisory. “In appliance mode BIG-IP, a successful exploit of this vulnerability can allow the attacker to cross a security boundary.”

Tracked as CVE-2023-22374 (CVSS score: 7.5/8.5), security researcher Ron Bowes of Rapid7 has been credited with discovering and reporting the flaw on December 6, 2022.
