CVE-2009-4140

HIGHCVSS v2 · 7.57.5—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 7.5 — v2 rates that HIGH (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:L/Au:N/C:P/I:P/A:P. 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 75.8% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

Unrestricted file upload vulnerability in ofc_upload_image.php in Open Flash Chart v2 Beta 1 through v2 Lug Wyrm Charmer, as used in Piwik 0.2.35 through 0.4.3, Woopra Analytics Plugin before 1.4.3.2, and possibly other products, when register_globals is enabled, allows remote authenticated users to execute arbitrary code by uploading a file with an executable extension through the name parameter with the code in the HTTP_RAW_POST_DATA parameter, then accessing it via a direct request to the file in tmp-upload-images/.
