CVE-2011-1772

LOWCVSS v2 · 2.62.6—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 2.6 — v2 rates that LOW (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:H/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 33.3% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

A fix is available — apply it.

Multiple cross-site scripting (XSS) vulnerabilities in XWork in Apache Struts 2.x before 2.2.3, and OpenSymphony XWork in OpenSymphony WebWork, allow remote attackers to inject arbitrary web script or HTML via vectors involving (1) an action name, (2) the action attribute of an s:submit element, or (3) the method attribute of an s:submit element.
