CVE-2014-0130
Ruby on Rails Directory Traversal Vulnerability
Description
CVE-2014-0130 is a high-severity path traversal vulnerability affecting Rails Ruby on Rails. Directory traversal vulnerability in actionpack/lib/abstract_controller/base.rb in the implicit-render implementation in Ruby on Rails allows remote attackers to read arbitrary files via a crafted request. An attacker can exploit this flaw without authentication over the network. CISA has added this vulnerability to the Known Exploited Vulnerabilities catalog, confirming active exploitation in the wild. The EPSS score of 48.56% (97.7th percentile) indicates a significantly elevated exploitation probability.

Weakness Type
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Path Traversal (also known as Directory Traversal) is a vulnerability that occurs when software uses external input to construct a pathname intended to identify a file or directory located underneath a restricted parent directory, but fails to properly neutralize special elements such as ".. In the case of CVE-2014-0130, this weakness allows attackers to compromise Rails Ruby on Rails systems.

Impact Analysis
CVE-2014-0130 carries a CVSS 3.1 base score of 7.5 (HIGH), reflecting the serious risk it poses to affected environments. Successful exploitation can lead to complete compromise of data confidentiality, no direct integrity impact, and no direct availability impact. The attack vector is network-based with low complexity, meaning exploitation is straightforward and can be reliably repeated. Organizations running Rails Ruby on Rails face tangible risk of unauthorized access, data breaches, and operational disruption if this vulnerability remains unpatched.
Exploit Maturity
CVE-2014-0130 is listed in the CISA Known Exploited Vulnerabilities catalog with a remediation deadline of 2022-04-15, confirming that real-world exploitation has been observed. The EPSS score of 48.56% (97.7th percentile) places this vulnerability among those most likely to be exploited.
Remediation
- Apply updates per vendor instructions. This is the CISA-mandated remediation action and should be prioritized immediately.
- If patches cannot be applied immediately, restrict network access to the affected Ruby on Rails management interfaces to only trusted administrative networks using firewall rules or access control lists.
- Monitor vendor security advisories for additional updates and ensure a patch management process is in place for timely deployment.
- Conduct a thorough review of affected systems for signs of prior compromise, including unexpected user accounts, modified configurations, and unusual network activity.
- Implement defense-in-depth measures including network segmentation, intrusion detection systems, and continuous security monitoring for the affected infrastructure.
Technical Details
CVE-2014-0130 is exploitable remotely over the network without any prior authentication. Directory traversal vulnerability in actionpack/lib/abstract_controller/base.rb in the implicit-render implementation in Ruby on Rails allows remote attackers to read arbitrary files via a crafted request. The attack complexity is rated low, meaning no specialized conditions or preparation are needed beyond network access to the target. The scope is unchanged, meaning the impact is confined to the vulnerable component. The CVSS 3.1 base score of 7.5 reflects the combination of these factors and the potential for significant damage to affected systems.
