In TYPO3 faceted fulltext search (ke_search), the OOXML parsing of the file indexer does not disable external entity resolution. A crafted xlsx or pptx document placed in an indexed directory can cause local files to be read or outbound HTTP requests to be performed, with the retrieved content being written to the search index. This has been patched in versions 7.0.1, 6.6.1, 5.6.2 and 4.6.7.
In TYPO3 faceted fulltext search (ke_search), theadditional_tables configuration of the page and tt_content indexers accept arbitrary table and field names. A backend user with permission to edit indexer configurations can copy sensitive data from internal TYPO3 tables into the search index. This has been patched in versions 7.0.1, 6.6.1, 5.6.2 and 4.6.7.
In TYPO3 faceted fulltext search (ke_search), the file indexer does not normalize the configured directory path. A backend user with permission to edit indexer configurations can index documents from arbitrary locations on the server file system through path traversal sequences. This has been patched in versions 7.0.1, 6.6.1, 5.6.2 and 4.6.7.
The ke_search (aka Faceted Search) extension before 4.0.3, 4.1.x through 4.6.x before 4.6.6, and 5.x before 5.0.2 for TYPO3 allows XSS via indexed data.
The ke_search (aka Faceted Search) extension through 2.8.2, and 3.x through 3.1.3, for TYPO3 allows XSS.
