Credential disclosure via login parameter SQL injection
Published Mar 19, 2024 · Updated Aug 12, 2024
SQL injection in Netentsec NS-ASG Application Security Gateway 6.3 allows remote attackers to read stored gateway credentials. The /vpnweb/index.php login handler incorporates check_VirtualSiteId into an SQL expression without neutralizing SQL syntax; the published error-based payload queries ISCUserTable and returns username and password data through updatexml(). The endpoint processes the injected value during login, so no established account is required, and the demonstrated consequence is disclosure of gateway credential data.
