Permissions, Privileges, and Access Controls
The Debian GNU/Linux 033_-F_NO_SETSID patch for the Apache HTTP Server 1.3.34-4 does not properly disassociate httpd from a controlling tty when httpd is started interactively, which allows local users to gain privileges to that tty via a CGI program that calls the TIOCSTI ioctl.
CWE-264 - Permissions Privileges and Access Controls
CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
