CVE-2026-47871: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in VMware Avi Load Balancer
VMware Avi Load Balancer contains a directory traversal vulnerability. Flaws in file path validation allow malicious, authenticated network users to perform directory traversal attacks. 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)
AI Analysis
Technical Summary
CVE-2026-47871 is a directory traversal vulnerability in VMware Avi Load Balancer caused by improper validation of file paths. Authenticated network users can exploit this flaw to perform directory traversal attacks, potentially leading to unauthorized disclosure, modification, or deletion of files. The vulnerability affects versions 22.1.1 through 22.1.7, 30.1.1 through 30.2.6, 31.1.1 through 31.2.2, and version 32.1.1. Fixed versions include 30.2.7, 31.2.2-2p3, and 32.1.2. The CVSS v3.1 base score is 8.8, indicating high severity with network attack vector, low attack complexity, required privileges, and no user interaction.
Potential Impact
Successful exploitation allows authenticated users to perform directory traversal, potentially leading to full confidentiality, integrity, and availability impact on the affected system. This can result in unauthorized access to sensitive files, modification of system data, or disruption of service.
Mitigation Recommendations
A patch is available for this vulnerability. Users should upgrade to the fixed versions: 30.2.7, 31.2.2-2p3, or 32.1.2. Since this is a cloud service, VMware manages remediation for the cloud-hosted instances; customers should verify with VMware advisory for the current status of cloud service patching.
