Noroxi assessment
Priority: Monitor (action score 21/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 1.8% (FIRST EPSS); higher than 79% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: actionpack (RubyGems) 3.0.10.
Low priority for now. Upgrade to actionpack (RubyGems) 3.0.10 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
The template selection functionality in actionpack/lib/action_view/template/resolver.rb in Ruby on Rails 3.0.x before 3.0.10 and 3.1.x before 3.1.0.rc6 does not properly handle glob characters, which allows remote attackers to render arbitrary views via a crafted URL, related to a "filter skipping vulnerability."
