CVE-2010-0926

LOWCVSS v2 · 3.53.5—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 3.5 — 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:M/Au:S/C:P/I:N/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 30.5% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

The default configuration of smbd in Samba before 3.3.11, 3.4.x before 3.4.6, and 3.5.x before 3.5.0rc3, when a writable share exists, allows remote authenticated users to leverage a directory traversal vulnerability, and access arbitrary files, by using the symlink command in smbclient to create a symlink containing .. (dot dot) sequences, related to the combination of the unix extensions and wide links options.
