Permissions, Privileges, and Access Controls
xinetd does not enforce the user and group configuration directives for TCPMUX services, which causes these services to be run as root and makes it easier for remote attackers to gain privileges by leveraging another vulnerability in a service.
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.
