CVE-2014-0130 — Ruby on Rails Directory Traversal Vulnerability

Directory traversal vulnerability in actionpack/lib/abstract_controller/base.rb in the implicit-render implementation in Ruby on Rails before 3.2.18, 4.0.x before 4.0.5, and 4.1.x before 4.1.1, when certain route globbing configurations are enabled, allows remote attackers to read arbitrary files via a crafted request.

High

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

CISA KEV · Mar 25, 2022

How the score was calculated

Confirmed exploitation (CISA KEV)+35
EPSS 53.7% (30-day exploitation probability)+15
Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Red Hat Enterprise Linux Server, Red Hat Subscription Asset Manager, Rubyonrails Rails).
Treat as emergency remediation: the CVE is in CISA KEV (confirmed exploitation).
The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
EPSS ahead of 99% of scored CVEs: prioritize it in the patch queue.
Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.

Detection

Read off the CVSS vector and the weakness class. Starting points, not tested rules.

Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
Monitor file creation in web directories and paths with traversal sequences (../).

What should defenders know first?

CVE-2014-0130 is "Ruby on Rails Directory Traversal Vulnerability", rated High. It affects Enterprise Linux Server (Red Hat); versions are in the scope table. It is in CISA KEV: there is evidence of real-world exploitation. CVSS 7.5 describes technical severity. EPSS 53.70% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
