Horizon Alert
Summary of the vulnerability and why it matters
Certain versions of Ruby on Rails contain a directory traversal vulnerability. This flaw permits remote attackers to access and read arbitrary files on affected systems. The impact of this vulnerability can expose sensitive data that is stored on these systems.
- Vulnerable Ruby on Rails component
- Allows reading arbitrary files
- Exposes sensitive business data
Attack Path
How an attacker could exploit the issue
A directory traversal vulnerability exists in Ruby on Rails, impacting the implicit-render functionality within abstract_controller/base.rb. When specific route globbing configurations are active, remote attackers can exploit this flaw. By sending a specially crafted request, attackers can gain unauthorized access to read arbitrary files from the affected system. This could lead to the exposure of sensitive information.
- System is exposed externally.
- Attacker sends a crafted request.
- Attacker reads arbitrary files.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow attackers to access sensitive files on affected systems. The risk stems from the ability of remote attackers to read arbitrary files through crafted requests, potentially exposing organizational data. Organizations utilizing affected Ruby on Rails versions should consider this a significant concern.
- Likely attacker skill: Low
- Required access: None
- Business risk or urgency: High
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
