CVE-2013-2617 is a Command Injection vulnerability discovered in the Curl Gem for Ruby. This flaw allows attackers to execute arbitrary commands on a system by injecting malicious shell metacharacters into URLs processed by the gem. The vulnerability affects versions of the Curl Gem up to and including 0.0.9. A fix is available through upgrading to a patched version of the gem.
The impact of CVE-2013-2617 is significant due to the potential for remote command execution. An attacker who can craft a malicious URL can leverage this vulnerability to gain control of the underlying system. This could involve data theft, system compromise, or even complete system takeover. The ability to execute arbitrary commands provides a wide range of attack vectors, making this a high-risk vulnerability. Exploitation could lead to unauthorized access to sensitive data, modification of system configurations, and the installation of malware.
CVE-2013-2617 was publicly disclosed in 2017. While no active exploitation campaigns are explicitly documented, the vulnerability's ease of exploitation and the widespread use of Ruby in web applications make it a potential target. There are publicly available proof-of-concept exploits demonstrating the command injection vulnerability. It is not listed on the CISA KEV catalog.
Applications written in Ruby that rely on the Curl Gem for URL processing are at risk. This includes web applications, scripts, and automation tools. Specifically, older Ruby projects that haven't been updated in a while are particularly vulnerable, as they are more likely to be using outdated versions of the Curl Gem.
• ruby / server:
grep -r 'curl.rb' /path/to/your/ruby/projects | grep -i 'http://' # Look for URL processing in the vulnerable file• generic web:
curl -I 'http://your-application.com?url=;ls' # Attempt to trigger command injection via URL parameterdisclosure

The primary mitigation for CVE-2013-2617 is to upgrade to a patched version of the Curl Gem. Unfortunately, a specific fixed version is not provided in the data. If upgrading is not immediately feasible, consider implementing strict input validation on URLs processed by the Curl Gem. This should involve sanitizing user-supplied input to remove or escape any potentially malicious shell metacharacters. Web Application Firewalls (WAFs) configured to detect and block command injection attempts can also provide a layer of defense. Carefully review and restrict the permissions of the Ruby process running the application to limit the potential damage from a successful exploit.
