IMAP: Domino Set Quota
This signature detects attempts to modify the user quota on an IMAP server. Domino 6.5.0 and 6.5.1 allow any user to modify its quota regardless of its rights on the server.
Extended Description
IBM Lotus Domino server is reported to improperly allow users to alter their own mail storage quota values. A user's mailbox is assigned a quota to limit the amount of data that can be consumed by email on the server. This quota is assigned by the administrator of the application. An attacker could possibly use this vulnerability to raise their mailbox's quota to a very large amount, and then proceed to fill the mail servers storage device. This will result in a denial of service condition, where new mail will not be able to be stored on the full disk. Domino version 6.5.0 and 6.5.1 are reported vulnerable to this issue.
