Permissions, Privileges, and Access Controls
perms.cpp in March Hare Software CVSNT 2.0.58, 2.5.01, 2.5.02, 2.5.03 before build 3736, 2.5.04 before build 2862; CVS Suite 2.5.03, 2008 before build 3736, and 2009 before 3729 allows remote attackers to bypass the permissions check, modify arbitrary modules and directories within CVSROOT, and execute arbitrary code via a crafted branch name ACL, possibly related to incorrect inheritance.
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.
