CVE-2005-4126

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 1.8% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

UNVERIFIABLE, PRERELEASE NOTE: this issue describes a problem that can not be independently verified as of 20051208. Unspecified vulnerability in unspecified versions of Real Networks RealPlayer allows attackers to execute arbitrary code. NOTE: the information regarding this issue is extremely vague and does not provide any verifiable information. It has been posted by a reliable reporter with a prerelease disclosure policy. This item has only been assigned a CVE identifier for tracking purposes, and to serve as a concrete example for discussion of the newly emerging UNVERIFIABLE and PRERELEASE content decisions in CVE, which must be discussed by the Editorial Board. Without additional details or independent verification by reliable sources, it is possible that this item might be RECAST or REJECTED.
