CVE-2013-10059 in DIR-615H1
Summary
by MITRE • 08/02/2025
An authenticated OS command injection vulnerability exists in various D-Link routers (tested on DIR-615H1 running firmware version 8.04) via the tools_vct.htm endpoint. The web interface fails to sanitize input passed from the ping_ipaddr parameter to the tools_vct.htm diagnostic interface, allowing attackers to inject arbitrary shell commands using backtick encapsulation. With default credentials, an attacker can exploit this blind injection vector to execute arbitrary commands.

The vulnerability identified as CVE-2013-10059 represents a critical authenticated operating system command injection flaw discovered in D-Link router models, specifically affecting the DIR-615H1 with firmware version 8.04. This security weakness stems from inadequate input validation within the web-based administrative interface, creating a pathway for malicious actors to execute unauthorized system commands. The vulnerability manifests through the tools_vct.htm endpoint which processes diagnostic requests without properly sanitizing user-supplied input parameters, particularly the ping_ipaddr field that serves as the attack vector.
The technical implementation of this flaw involves the web application's failure to implement proper input sanitization measures when processing the ping_ipaddr parameter. Attackers can exploit this by crafting malicious input that utilizes backtick character encapsulation to inject shell commands directly into the underlying operating system. This blind command injection technique allows for arbitrary code execution with the privileges of the web server process, typically running with elevated system permissions. The vulnerability's authentication requirement means that an attacker must first obtain valid credentials, typically default administrator credentials, to access the vulnerable web interface before exploitation can occur.
The operational impact of this vulnerability extends beyond simple command execution, as it provides attackers with complete control over the affected router's functionality. Once exploited, adversaries can modify network configurations, redirect traffic, install malicious software, or establish persistent access points within the network infrastructure. The blind nature of the injection means that attackers cannot directly observe command output, requiring them to employ indirect methods such as DNS callbacks or network traffic analysis to verify successful exploitation. This vulnerability directly maps to CWE-77 and CWE-94 within the Common Weakness Enumeration framework, specifically addressing improper input validation and command injection weaknesses that have been consistently identified as high-risk security flaws in network infrastructure devices.
Mitigation strategies for CVE-2013-10059 require immediate implementation of multiple security controls to protect affected D-Link router deployments. Network administrators should prioritize firmware updates from D-Link to address the underlying validation issues, while simultaneously implementing network segmentation to limit access to administrative interfaces. The principle of least privilege should be enforced by restricting access to the web management interface to authorized personnel only, utilizing strong authentication mechanisms and disabling default credentials immediately. Additional protective measures include implementing network access controls through firewalls to block unauthorized access to the router's administrative ports, monitoring network traffic for suspicious command injection patterns, and establishing regular security assessments to identify similar vulnerabilities in other network infrastructure components. These measures align with ATT&CK technique T1059.001 for command and script interpretation, emphasizing the importance of input validation and access control in preventing unauthorized system compromise.
