CVE-2011-4319

MEDIUMCVSS v2 · 4.34.3—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 4.3 — v2 rates that MEDIUM (v2 bands: LOW 0.0–3.9 / MEDIUM 4.0–6.9 / HIGH 7.0–10.0; v2 has no CRITICAL band). Vector AV:N/AC:M/Au:N/C:N/I:P/A:N. CVSS v2 is an older, coarser metric than v3.1/v4.0 (no Scope, no User Interaction, no Attack Requirements), so it is not directly comparable to a v3 or v4 score. NVD has never re-scored this record under v3. EPSS predicts 1.6% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

Cross-site scripting (XSS) vulnerability in the i18n translations helper method in Ruby on Rails 3.0.x before 3.0.11 and 3.1.x before 3.1.2, and the rails_xss plugin in Ruby on Rails 2.3.x, allows remote attackers to inject arbitrary web script or HTML via vectors related to a translations string whose name ends with an "html" substring.
