MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1505 Server Software Component Persistence
Adversaries may abuse legitimate extensible development features of servers to establish persistent access to systems.
Why these techniques?

SQL injection in the web management interface (/protocol/firewall/uploadfirewall.php) of the NS-ASG Application Security Gateway enables exploitation of a public-facing application (T1190) and abuse of a server software component (T1505) to execute arbitrary SQL queries for data discovery, as demonstrated in the POC and noted in advisories.
