Avi Load Balancer contains an unauthenticated blind SQL Injection vulnerability which was privately reported to VMware. Patches are available to remediate this vulnerability in affected VMware products. A malicious user with network access may be able to use specially crafted SQL queries to gain database access.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
