A Vulnerability in SonicWall SMA 100 Series Could Allow for SQL Injection
by CIRT Team
DESCRIPTION:
A vulnerability has been discovered in the SonicWall SMA 100 Series,
which could allow for SQL injection. The SonicWall SMA 100 Series is a
unified secure access gateway that enables organizations to provide
access to any application, anytime, from anywhere and any devices,
including managed and unmanaged. Successful exploitation of this
vulnerability could result in SQL injection, which enables the retrieval
of admin credentials. Afterwards, this retrieval can pivot into a
remote-code execution attack. Depending on the privileges associated
with the application, an attacker could install programs; view, change,
or delete data; or create new accounts with full user rights.
