Appliance-mode escape via undisclosed REST command injection
Published May 5, 2022 · Updated Sep 17, 2024
Command injection in F5 BIG-IP allows remote authenticated users with Administrator access to bypass Appliance mode restrictions. The iControl REST endpoint accepts command elements that Appliance mode should block, but F5 has not disclosed the endpoint or failing neutralization logic. Exploitation requires network access to iControl REST, an authenticated Administrator account, and Appliance mode; it compromises confidentiality and integrity without reported service interruption.
