CVE-2005-1543

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 66.9% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

Multiple stack-based and heap-based buffer overflows in Remote Management authentication (zenrem32.exe) on Novell ZENworks 6.5 Desktop and Server Management, ZENworks for Desktops 4.x, ZENworks for Servers 3.x, and Remote Management allows remote attackers to execute arbitrary code via (1) unspecified vectors, (2) type 1 authentication requests, and (3) type 2 authentication requests.
