Overview<\/strong><\/p>\n

The discovery of a critical vulnerability (CVE-2025-4350) in D-Link DIR-600L up to version 2.07B01 poses a significant threat to users of this outdated and unsupported product. This vulnerability, which affects the wake_on_lan function, allows an attacker to initiate a command injection attack remotely, leading to potential system compromise or data leakage. Understanding the nature of this vulnerability, its potential impact, and steps for mitigation is critical for all cybersecurity<\/a> professionals, especially those managing networks still running these unsupported devices.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-4350
\nSeverity: Critical (CVSS 8.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

D-Link DIR-600L<\/a> | Up to 2.07B01<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability lies in the manipulation<\/a> of the ‘host’ argument in the wake_on_lan function. An attacker can exploit this weakness by sending a specially crafted request to the affected device, which includes malicious commands hidden within the ‘host’ argument. The device then executes these commands, potentially leading to system compromise or unauthorized access to sensitive data<\/a>.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a conceptual example of how the vulnerability might be exploited using a HTTP request:<\/a><\/p>\n

POST \/wake_on_lan HTTP\/1.1\nHost: vulnerable.example.com\nContent-Type: application\/json\n{ \"host\": \"validHost; rm -rf \/\" }<\/code><\/pre>\n
In this conceptual example, the malicious payload is the command (`rm -rf \/`) appended after a semi-colon in the ‘host’ argument. This command, when executed, would delete all files in the system, illustrating the severity of the potential impact of this vulnerability<\/a>.<\/p>\n
Mitigation<\/strong><\/p>\n
Given that D-Link no longer supports the affected products, applying a vendor patch may not be possible. As a temporary mitigation, it is recommended to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block potential exploit attempts. However, the best course of action would be to replace these unsupported devices with newer, secure models that receive regular security updates from the vendor.<\/p>\n","protected":false},"excerpt":{"rendered":"
