CVE-2011-4642

MEDIUMCVSS v2 · 4.64.6—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 4.6 — 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:H/Au:S/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 28.9% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

mappy.py in Splunk Web in Splunk 4.2.x before 4.2.5 does not properly restrict use of the mappy command to access Python classes, which allows remote authenticated administrators to execute arbitrary code by leveraging the sys module in a request to the search application, as demonstrated by a cross-site request forgery (CSRF) attack, aka SPL-45172.
