CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as very critical, was found in D-Link DIR-645 up to 1.04b12 (Router Operating System). Affected is an unknown part of the file Wired/Wireless of the component Interface. The manipulation with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The D-Link DIR-645 Wired/Wireless Router Rev. Ax with firmware 1.04b12 and earlier allows remote attackers to execute arbitrary commands via a GetDeviceSettings action to the HNAP interface.

The weakness was published 02/23/2015 (Website). The advisory is shared for download at securityadvisories.dlink.com. This vulnerability is traded as CVE-2015-2051 since 02/23/2015. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 04/22/2026). The MITRE ATT&CK project declares the attack technique as T1202.

A public exploit has been developed by Metasploit in Ruby and been published 4 months after the advisory. The exploit is shared for download at securityfocus.com. It is declared as attacked. As 0-day the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 84086 (D-Link Router HNAP GetDeviceSettings Remote Command Execution), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CGI abuses and running in the context r. The Nessus plugin is testing the existence of the vulnerability with the following NASL code:

res = http_send_recv3(
  method       : "POST",
  item         : dir,
  port         : port,
  add_headers  : make_array(
    "Content-Length", '1\r\n' +
    "SOAPAction:http://purenetworks.com/HNAP1/GetDeviceSettings/1;" + exploit_command + ';'
  )
);

# This is used in the report later
exploit_request = http_last_sent_request();

# Check if the file was uploaded successfully
res = NULL;
res = http_send_recv3(
  method: "GET",
  item: dir + file,
  port: port,
  exit_on_fail:TRUE
);

This issue was added on 02/10/2022 to the CISA Known Exploited Vulnerabilities Catalog with a due date of 08/10/2022:

The impacted product is end-of-life and should be disconnected if still in use.
