Incomplete blacklist vulnerability in config.template.php in vtiger CRM before 5.2.1 allows remote authenticated users to execute arbitrary code by using the draft save feature in the Compose Mail component to upload a file with a .phtml extension, and then accessing this file via a direct request to the file in the storage/ directory tree.
CVE-2010-3909
This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 6.0 — 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:M/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 1.6% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
