IBM WebSphere MQ 6.0 before 6.0.2.8 and 7.0 before 7.0.1.0 does not properly handle long group names, which might allow local users to gain privileges by leveraging combinations of group names with the same initial substring.
The Web Gateway component in IBM WebSphere MQ File Transfer Edition 7.0.4 and earlier allows remote authenticated users to read files of arbitrary users via vectors involving a username in a URI, as demonstrated by a modified metadata=fteSamplesUser field to the /transfer URI.
