GHSA-6qvp-39mm-95v8 com.xwiki.confluencepro:application-confluence-migrator-pro-ui Remote Code Execution via unescaped translations

• Maven com.xwiki.confluencepro:application-confluence-migrator-pro-ui: >= 1.0, < 1.2.0 → fixed in 1.2.0

Impact A user that doesn't have programming rights can execute arbitrary code when creating a page using the Migration Page template. A possible attack vector is the following: • Create a page and add the following content: ``` confluencepro.job.question.advanced.input={{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("hello from groovy!"){{/groovy}}{{/async}} ``` • Use the object editor to add an object of type `XWiki.TranslationDocumentClass` with scope `USER`. • Access an unexisting page using the `MigrationTemplate` ``` http://localhost:8080/xwiki/bin/edit/Page123?template=ConfluenceMigratorPro.Code.MigrationTemplate ``` It is expected that `{{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("hello from groovy!"){{/groovy}}{{/async}}` will be present on the page, however, `hello from groovy` will be printed. Patches The issue will be fixed as part of v1.2. The fix was added with commit 35cef22 Workarounds There are no known workarounds besides upgrading. References No references.
