PeopleSoft Gateway Administration servlet (gateway.administration) in PeopleTools 8.43 and earlier allows remote attackers to obtain the full pathnames for server-side include (SSI) files via an HTTP request with an invalid value.
The Application Messaging Gateway for PeopleTools 8.1x before 8.19, as used in various PeopleSoft products, allows remote attackers to read arbitrary files via certain XML External Entities (XXE) fields in an HTTP POST request that is processed by the SimpleFileHandler handler.
