Detailsinfo

A vulnerability was found in Linux Kernel up to 2.6.22.2 (Operating System). It has been classified as problematic. Affected is an unknown functionality of the component AACRAID Driver. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. The impact remains unknown. CVE summarizes:

The (1) aac_cfg_open and (2) aac_compat_ioctl functions in the SCSI layer ioctl path in aacraid in the Linux kernel before 2.6.23-rc2 do not check permissions for ioctls, which might allow local users to cause a denial of service or gain privileges.

The weakness was presented 08/06/2007 with Kernel-Development (Website). The advisory is shared for download at kernel.org. This vulnerability is traded as CVE-2007-4308 since 08/13/2007. The attack can only be done within the local network. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1068.

It is declared as proof-of-concept. As 0-day the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 37953 (CentOS 4 : kernel (CESA-2007:0939)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 155181 (Oracle Enterprise Linux Kernel Security and Bug Fix Update (ELSA-2007-1049)).
