XWiki Confluence Migrator Pro helps admins to import confluence packages into their XWiki instance.
CVSS 9.1 Critical EPSS 0.7% · p51
Should you act?
Critical, preconditions apply
Severe if exploited, but exploitation needs conditions that may not apply to you. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.7%, percentile 51: FIRST’s model estimates a 0.7% chance of exploitation activity in the next 30 days, higher than 51% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs an account (high (admin)). Exposure depends on who can log in.
- Only applies if your dependency tree includes
com.xwiki.confluencepro:application-confluence-migrator-pro-ui(Maven) >= 1.0, < 1.2.0, fixed in 1.2.0. Check your lockfile, including transitive dependencies.
What it is
XWiki Confluence Migrator Pro helps admins to import confluence packages into their XWiki instance. A user that doesn't have programming rights can execute arbitrary code due to an unescaped translation when creating a page using the Migration Page template. This vulnerability is fixed in 1.2.0.
From the GitHub advisory
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:
Use the object editor to add an object of type XWiki.TranslationDocumentClass with scope USER. Access an unexisting page using the 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.
