DescriptionNVD

VMware Avi Load Balancer contains a privilege escalation vulnerability. A malicious authenticated user with network access may be able to execute remote code.

Affected versions: 32.1.1 (fixed in 32.1.2) 31.1.1 through 31.2.2 (fixed in 31.2.2-2p3) 30.1.1 through 30.2.6 (fixed in 30.2.7) 22.1.1 through 22.1.7 (fixed in 30.2.7)

AnalysisAI

Privilege escalation in VMware Avi Load Balancer exposes authenticated, network-accessible users to remote code execution across a wide version range spanning 22.1.x through 32.1.x. The CVSS 8.8 rating reflects low-complexity, low-privilege network exploitation yielding full confidentiality, integrity, and availability impact on affected systems. No public exploit code has been identified and the vulnerability is absent from CISA KEV; EPSS at 0.39% (31st percentile) confirms limited active exploitation pressure at time of analysis.

Technical ContextAI

VMware Avi Load Balancer (CPE: cpe:2.3:a:vmware:avi_load_balancer:*:*:*:*:*:*:*:*) is a software-defined application delivery controller providing load balancing, WAF, and analytics capabilities, now maintained under Broadcom following the VMware acquisition. The root cause is CWE-269 (Improper Privilege Management), meaning the platform insufficiently enforces privilege boundaries - a principal holding low-privilege credentials can traverse into higher-privilege execution contexts sufficient to run arbitrary code. The AV:N vector indicates the vulnerable privilege escalation path is reachable via the network-exposed management or API plane, not confined to local OS-level access.

RemediationAI

The primary fix is to upgrade to a patched release per the Broadcom advisory at https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/37926: upgrade to 32.1.2 if running 32.1.1; upgrade to 31.2.2-2p3 if running 31.1.1-31.2.2; upgrade to 30.2.7 if running 30.1.1-30.2.6 or 22.1.1-22.1.7. Where immediate patching is not feasible, restrict network access to the Avi Load Balancer management and API interfaces to trusted administrative subnets or VPN segments, reducing the effective attack surface - note this does not eliminate risk if insider-threat scenarios apply. Audit all platform accounts and revoke or demote any unnecessary low-privilege accounts, since PR:L is the prerequisite for exploitation. Enforcing MFA for all platform logins further raises the bar for credential-based access. These compensating controls reduce but do not eliminate risk and should not substitute for patching.
