CVE-2023-5681Public exploitNetwork attack vector

Database disclosure via unsanitized ResId SQL input

Published Oct 20, 2023 · Updated Sep 17, 2024

SQL injection in Netentsec NS-ASG Application Security Gateway 6.3 allows remote authenticated users to read database data. The administrative list_addr_fwresource_ip.php handler passes the ResId[] form value into a deletion query without validating or neutralizing SQL syntax. An administrative session is required; the published proof of concept uses a crafted delete action to disclose the database name, while broader effects are unverified.
