About Broadcom Vmware Avi Load Balancer
CVE-2026-47870 affects Broadcom Vmware Avi Load Balancer, a product from Broadcom. Before acting, confirm where Broadcom Vmware Avi Load Balancer runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: 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)
The weakness class is Improper Privilege Management. Privileges are assigned or checked incorrectly.
Based on its CVSS vector, the flaw can be reached over the network, needs some level of access, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.

How to detect it
- Inventory every instance of Broadcom Vmware Avi Load Balancer and record the running version against the affected range above.
- Check external attack surface scans for internet facing instances of the component.
- Review logs on affected systems for unusual requests, errors or new processes around the vulnerable function.
- Confirm with an authenticated vulnerability scan once your scanner has a check for this CVE.
How to fix it
- Apply the fixed version of Broadcom Vmware Avi Load Balancer named in the vendor advisory.
- If patching must wait, restrict network access to the affected service and put it behind authentication or a web application firewall rule.
- Rescan after the change to prove the exposure is gone, then close the ticket.

Frequently asked questions
Related CVEs
In Brocade ASCG before 3.5.0, a local unauthorized user on the ASCG VM who can issue a request to the SANnav host network namespace can extract stored management credentials for onboarded SANnav instances and compromise connected Brocade SANnav servers or managed Brocade Fibre Channel switches.
A vulnerability in the SupportLink API authentication component of Brocade ASCG versions prior to 3.5.0 allows an attacker to bypass authentication across deployments due to the use of a hard coded cryptographic key.
When Brocade ASCG before 3.5.0 processes support bundle archives ingested from remote compromised endpoints, the application fails to sanitize path traversal sequences contained within archive entries prior to extraction. An unauthenticated remote attacker capable of sending or intercepting ingested archive files can leverage this flaw to write arbitrary files to restricted locations on the underlying host, potentially leading to remote code execution.
An authentication flaw exists in the Brocade ASCG administrative management service component. An unauthenticated network user can issue direct API requests to perform privileged actions, including accessing sensitive system configuration mapping data, modifying managed device inventories, and altering operational settings. This vulnerability affects all versions of Brocade ASCG before 3.5.0.
Brocade ASCG before 3.5.0 has a well-known Brocade default password embedded in a script distributed to every customer. Any local authenticated user with read access to the installation path can discover this credential and perform privilege escalation on affected Open Virtual Appliance (OVA) deployments, where default configuration settings remain in place.
A path traversal vulnerability exists in the HTTP service component of Brocade ASCG versions before 3.5.0. An unauthenticated attacker on the local network could send a manipulated API request to the service endpoint bypassing path restrictions to arbitrary file read, file write, or file deletion operations.
