Analysis Summary

Broadcom has issued a security advisory warning of a high-severity vulnerability in VMware Avi Load Balancer, identified as CVE-2025-22217, with a CVSS score of 8.6. The flaw is classified as an unauthenticated blind SQL injection, meaning attackers with network access could exploit it using specially crafted SQL queries to gain unauthorized access to the database. This could lead to data breaches, unauthorized modifications, or further exploitation of the system.

The vulnerability was discovered and reported by security researchers, The affected versions include VMware Avi Load Balancer 30.1.1, 30.1.2, 30.2.1, and 30.2.2, with fixes available in versions 30.1.2-2p2, 30.2.1-2p5, and 30.2.2-2p2. Notably, versions 22.x and 21.x are not impacted by this flaw. Broadcom has explicitly mentioned that users on version 30.1.1 need to first upgrade to 30.1.2 or later before applying the security patch to ensure proper remediation. This highlights the urgency for administrators to check their software versions and implement the fixes promptly.

There are no available workarounds to mitigate the risk posed by CVE-2025-22217, making it essential for affected organizations to update their VMware Avi Load Balancer instances immediately. Failure to do so could leave them vulnerable to potential exploitation, especially given that SQL injection vulnerabilities are commonly used for data exfiltration, privilege escalation, or persistence within a network. Since this is an unauthenticated attack vector, it presents a significant risk to any exposed systems.

Organizations relying on VMware Avi Load Balancer should prioritize patching as part of their security strategy to prevent potential attacks. Given the severity of the vulnerability and the lack of alternative solutions, updating to the patched versions is the only effective measure. Companies should also review their security configurations and monitoring systems to detect any suspicious activities that might indicate exploitation attempts. Broadcom’s advisory serves as a critical reminder of the importance of timely patch management to safeguard infrastructure from evolving cyber threats.
