CVE-2009-0243
Status: ModifiedHigh (7.2)—
Microsoft Windows does not properly enforce the Autorun and NoDriveTypeAutoRun registry values, which allows physically proximate attackers to execute arbitrary code by (1) inserting CD-ROM media, (2) inserting DVD media, (3) connecting a USB device, and (4) connecting a Firewire device; (5) allows user-assisted remote attackers to execute arbitrary code by mapping a network drive; and allows user-assisted attackers to execute arbitrary code by clicking on (6) an icon under My Computer\Devices with Removable Storage and (7) an option in an AutoPlay dialog, related to the Autorun.inf file. NOTE: vectors 1 and 3 on Vista are already covered by CVE-2008-0951.
CVSS
- Version: 2.0
- Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
- Base score: 7.2
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 6.28%
- Percentile among all scored CVEs: 93
- Score date: 10/7/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
