0.10.0
CVE-2013-1801 is a security vulnerability affecting versions of the httparty Ruby gem prior to 0.10.0. This flaw allows attackers to inject objects and potentially execute arbitrary code through improper handling of string casts. The vulnerability stems from httparty's reliance on Action Pack's YAML type conversion, creating a pathway for exploitation. A fix is available in version 0.10.0.
An attacker can exploit CVE-2013-1801 to achieve remote code execution on systems utilizing vulnerable versions of the httparty gem. This is accomplished by crafting malicious input that leverages the gem's YAML type conversion functionality. Successful exploitation could lead to complete system compromise, including data theft, modification, or destruction. The vulnerability also presents a denial-of-service risk, as an attacker could trigger excessive memory and CPU consumption, rendering the system unresponsive. The similarity to CVE-2013-0156 highlights the potential for widespread exploitation if not addressed promptly.
CVE-2013-1801 was published in 2017, though the vulnerability itself dates back to 2013. Public proof-of-concept exploits are available, indicating a relatively low barrier to entry for attackers. While not currently listed on CISA KEV, the vulnerability's potential for remote code execution warrants careful attention. The similarity to CVE-2013-0156 suggests that attackers may be actively scanning for vulnerable systems.
Applications and systems utilizing the httparty gem in Ruby, particularly those handling external data or user input, are at risk. This includes web applications, APIs, and any Ruby scripts that rely on httparty for making HTTP requests. Legacy applications using older versions of Ruby and its dependencies are particularly vulnerable.
• ruby / gem: gem list httparty to check installed version. If ≤0.9.0, the system is vulnerable.
• ruby / gem: Inspect application code for usage of httparty and potential vulnerable code paths involving YAML parsing.
• ruby / system: Monitor system logs for unusual process activity or memory consumption related to Ruby applications using httparty.

The primary mitigation for CVE-2013-1801 is to upgrade the httparty gem to version 0.10.0 or later. If upgrading is not immediately feasible due to compatibility issues or breaking changes, consider implementing input validation to sanitize data before passing it to httparty. While a direct WAF rule is unlikely, carefully scrutinizing YAML payloads for suspicious object constructions can provide a layer of defense. After upgrading, confirm the fix by attempting to trigger the vulnerable code path with a known malicious payload and verifying that it is now properly handled.
