In the /HNAP1/SetRouterSettings message, the RemotePort parameter is vulnerable, and the vulnerability affects D-Link DIR-818LW Rev.A 2.05.B03 and DIR-822 B1 202KRb06 devices. In the SetRouterSettings.php source code, the RemotePort parameter is saved in the $path_inf_wan1."/web" internal configuration memory without any regex checking. And in the IPTWAN_build_command function of the iptwan.php source code, the data in $path_inf_wan1."/web" is used with the iptables command without any regex checking. A vulnerable /HNAP1/SetRouterSettings XML message could have shell metacharacters in the RemotePort element such as the `telnetd` string.

[CRITICAL] Top CVEs to Patch: Insights from the 2022 Unit 42 Network Threat Trends Research Report
## Executive Summary
Tens of thousands of vulnerabilities are reported every year, but not all are used by threat actors in real-world attacks. There are many reasons for this: a proof of concept (PoC) may not be available for attackers to weaponize, it may be too difficult to exploit the vulnerability, there may be a lack of accessible vulnerable software on the internet, or attackers may simply deem a vulnerability not worth exploiting due to low impact. Real-world defenders need real-world data on which vulnerabilities attackers are choosing to exploit – and where to focus protections.
In the 2022 Unit 42 Network Threat Trends Research Report, we’ve used data captured by the Palo Alto Networks Advanced Threat Prevention security service on Next-Generation Firewall and Prisma SASE from

# Executive Summary
Unit 42 researchers analyzed network attack trends over Winter 2020 and discovered many interesting exploits in the wild. During the period of Nov. 2020 to Jan. 2021, the majority of the attacks we observed were classified as critical (75%), compared to the 50.4% we reported in the fall of 2020. Several newly observed exploits, including CVE-2020-28188, CVE-2020-17519, and CVE-2020-29227, have emerged and were continuously being exploited in the wild as of late 2020 to early 2021.
This blog provides details of the newly observed exploits as well as a dive deep into the exploitation analysis, vendor analysis, attack origin, and attack category distribution.
