14
FAUCET Score

CVE-2005-1399 describes a local privilege escalation vulnerability in FreeBSD versions 4.6 through 4.11 and 5.x through 5.4. The flaw stems from insecure default permissions on the /dev/iir device, enabling local users to execute restricted ioctl calls. This allows unauthorized reading or modification of data on hardware controlled by the iir driver, leading to potential confidentiality, integrity, and availability impacts. With a CVSS score of 4.6 (AV:L/AC:L/Au:N/C:P/I:P/A:P), it is a low-complexity local attack. There is no known active exploitation, publicly available exploit code, or significant community discussion surrounding this vulnerability.
