- →Look for GET requests to /ajax/networking/get_netcfg.php where the 'iface' parameter contains shell metacharacters such as ';' ↗
- →Use Shodan/FOFA favicon hash to identify exposed RaspAP instances: favicon hash -1465760059
- →Exploitation can be confirmed via out-of-band HTTP callback (interactsh/OAST) triggered by injected curl command with whoami output in the URL path
- →Response body containing 'DHCPEnabled' confirms the endpoint is reachable and vulnerable
- →Interactsh/OAST request path regex 'GET \/([a-z-]+) HTTP' can be used to extract the whoami output from the callback
- ·The vulnerability is unauthenticated — no session or credentials are required to exploit the endpoint
- ·Affected versions are strictly RaspAP 2.6 through 2.6.5; versions above 2.6.5 are not affected

[CRITICAL] Network Security Trends: August-October 2021
## Executive Summary
Unit 42 researchers continually observe network attacks and search for insights that can assist defenders. Here, we summarize key trends from August-October 2021. In the following sections, we present our analysis of the most recently published vulnerabilities, including the severity distribution. We also classify vulnerabilities to provide a clear view of the prevalence of, say, cross-site scripting or denial of service.
Additionally, we provide insight into how the vulnerabilities are actively exploited in the wild based on real-world data collected from Palo Alto Networks Next-Generation Firewalls. For example, we chart a timeframe showing how frequently the most commonly exploited vulnerabilities were attacked through networks and the locations from which the att
