Rails Ruby on vulnerability
Directory traversal vulnerability in Ruby on Rails Action View allows remote attackers to read arbitrary files via path manipulation.
Verdict
Today item — known-exploited.
A path traversal flaw in Rails Action View enables unauthenticated remote file disclosure. The vulnerability permits attackers to escape intended directory boundaries and access sensitive application or system files, posing significant confidentiality risk.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
3 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2022-03-25).
Probability (EPSS)
EPSS 0.95537 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Rails, Ruby on Rails. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-22 Path Traversal — weakness family: Path traversal / file.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious request containing directory traversal sequences targeting the Rails view rendering engine.
Business
Sensitive application source code, configuration files, and credentials become accessible to unauthorized parties.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I read arbitrary files from the application server by exploiting insufficient path validation in Action View.
Business
Exposure of private keys, database credentials, and proprietary logic accelerates secondary compromise and data breach scope.
3
Lateral reach — past segmentation narrative 3
Attacker
I exfiltrate system files and application secrets discovered through repeated traversal attempts.
Business
Attackers gain sufficient intelligence to pivot to backend systems, databases, and infrastructure components.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
