CVE-2014-9682 · Severity: info · CVSS 9.8 · Published 2017-10-24

The dns-sync Node.js library is used to perform DNS lookups. A vulnerability in the resolve function allows attackers to inject shell commands through specially crafted hostnames, leading to arbitrary command execution on systems using the library.

Technologies: [dns-sync (npm)](https://junglewise.ai/threats/technologies/dns-sync). Vendors: [npm](https://junglewise.ai/threats/vendors/npm).

## Technical details

The dns-sync Node.js library versions before 0.1.1 contain a command injection vulnerability (CWE-77) in the resolve() API function. The vulnerability exists because user-supplied hostnames are passed directly into a shell command without proper sanitization. The vulnerable code constructs a shell command by concatenating the hostname argument with a node script path, then executes it via shell.exec(). An attacker can inject shell metacharacters (such as command substitution syntax like $(command)) into the hostname argument to execute arbitrary commands with the privileges of the Node.js process. No authentication or special privileges are required; any code calling the resolve() function with untrusted input is vulnerable. The vulnerability was fixed in version 0.1.1.
