Permissions, Privileges, and Access Controls
admin.php in UploadImage 1.0 does not check for the original password before making a change to a new password, which allows remote attackers to gain administrator privileges via the pass parameter in a nopass (Set Password) action.
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.
