Xwiki: >> Xwiki >> 10.11.7 Security Vulnerabilities
XWiki is a generic wiki platform. In versions starting from 1.6-milestone-1 to before 15.10.16, 16.4.6, and 16.10.1, it is possible for a user with SCRIPT right to escape from the HQL execution context and perform a blind SQL injection to execute arbitrary SQL statements on the database backend. Depending on the used database backend, the attacker may be able to not only obtain confidential information such as password hashes from the database, but also execute UPDATE/INSERT/DELETE queries. This issue has been patched in versions 16.10.1, 16.4.6 and 15.10.16. There is no known workaround, other than upgrading XWiki. The protection added to this REST API is the same as the one used to validate complete select queries, making it more consistent. However, while the script API always had this protection for complete queries, it's important to note that it's a very strict protection and some valid, but complex, queries might suddenly require the author to have programming right.

XWiki is a generic wiki platform. In versions starting from 1.8 and prior to 15.10.16, 16.4.6, and 16.10.1, it is possible for a remote unauthenticated user to escape from the HQL execution context and perform a blind SQL injection to execute arbitrary SQL statements on the database backend, including when "Prevent unregistered users from viewing pages, regardless of the page rights" and "Prevent unregistered users from editing pages, regardless of the page rights" options are enabled. Depending on the used database backend, the attacker may be able to not only obtain confidential information such as password hashes from the database, but also execute UPDATE/INSERT/DELETE queries. This issue has been patched in versions 16.10.1, 16.4.6 and 15.10.16. There is no known workaround, other than upgrading XWiki.

XWiki Platform is a generic wiki platform. A vulnerability in versions from 5.0 to 16.7.1 affects users with Message Stream enabled and a wiki configured as closed from selecting "Prevent unregistered users to view pages" in the Administrations Rights. The vulnerability is that any message sent in a subwiki to "everyone" is actually sent to the farm: any visitor of the main wiki will be able to see that message through the Dashboard, even if the subwiki is configured to be private. This issue will not be patched as Message Stream has been deprecated in XWiki 16.8.0RC1 and is not maintained anymore. A workaround for this issue involves keeping Message Stream disabled by default. It's advised to keep it disabled from Administration > Social > Message Stream.

XWiki Platform is a generic wiki platform. Prior to 15.10.14, 16.4.6, and 16.10.0-rc-1, it's possible for an user to get access to private information through the REST API - but could also be through another API - when a sub wiki is using "Prevent unregistered users to view pages". The vulnerability only affects subwikis, and it only concerns specific right options such as "Prevent unregistered users to view pages". or "Prevent unregistered users to edit pages". It's possible to detect the vulnerability by enabling "Prevent unregistered users to view pages" and then trying to access a page through the REST API without using any credentials. The vulnerability has been patched in XWiki 15.10.14, 16.4.6 and 16.10.0RC1.

XWiki Platform is a generic wiki platform. Prior to 15.10.14, 16.4.6, and 16.10.0-rc-1, protected pages are listed when requesting the REST endpoints /rest/wikis/[wikiName]/pages even if the user doesn't have view rights on them. It's particularly true if the entire wiki is protected with "Prevent unregistered user to view pages": the endpoint would still list the pages of the wiki, though only for the main wiki. The problem has been patched in XWiki 15.10.14, 16.4.6, 16.10.0RC1. In those versions the endpoint can still be requested but the result is filtered out based on pages rights.

XWiki Platform is a generic wiki platform. Starting in version 9.7-rc-1 and prior to versions 15.10.11, 16.4.1, and 16.5.0, any user with an account can perform arbitrary remote code execution by adding instances of `XWiki.WikiMacroClass` to any page. This compromises the confidentiality, integrity and availability of the whole XWiki installation. This vulnerability has been fixed in XWiki 15.10.11, 16.4.1 and 16.5.0. It is possible to manually apply the patch to the page `XWiki.XWikiSyntaxMacrosList` as a workaround.

XWiki Platform is a generic wiki platform. Starting in version 2.3 and prior to versions 15.10.9, 16.3.0, any user with script rights can perform arbitrary remote code execution by adding instances of `XWiki.ConfigurableClass` to any page. This compromises the confidentiality, integrity and availability of the whole XWiki installation. This has been patched in XWiki 15.10.9 and 16.3.0. No known workarounds are available except upgrading.

XWiki Platform is a generic wiki platform. Starting in version 1.2-milestone-2 and prior to versions 15.10.9 and 16.3.0, any user with an account on the main wiki could run scheduling operations on subwikis. To reproduce, as a user on the main wiki without any special right, view the document `Scheduler.WebHome` in a subwiki. Then, click on any operation (*e.g.,* Trigger) on any job. If the operation is successful, then the instance is vulnerable. This has been patched in XWiki 15.10.9 and 16.3.0. As a workaround, those who have subwikis where the Job Scheduler is enabled can edit the objects on `Scheduler.WebPreferences` to match the patch.

XWiki Platform is a generic wiki platform. Starting in version 6.3-milestone-2 and prior to versions 13.10.5 and 14.3-rc-1, in `getdocument.vm`; the ordering of the returned documents is defined from an unsanitized request parameter (request.sort) and can allow any user to inject HQL. Depending on the used database backend, the attacker may be able to not only obtain confidential information such as password hashes from the database, but also execute UPDATE/INSERT/DELETE queries. This has been patched in 13.10.5 and 14.3-rc-1. There is no known workaround, other than upgrading XWiki.

XWiki Platform is a generic wiki platform. Starting in version 3.3-milestone-1 and prior to versions 15.10.9 and 16.3.0, on instances where `Extension Repository Application` is installed, any user can execute any code requiring `programming` rights on the server. This vulnerability has been fixed in XWiki 15.10.9 and 16.3.0. Since `Extension Repository Application` is not mandatory, it can be safely disabled on instances that do not use it as a workaround. It is also possible to manually apply the patches from commit 8659f17d500522bf33595e402391592a35a162e8 to the page `ExtensionCode.ExtensionSheet` and to the page `ExtensionCode.ExtensionAuthorsDisplayer`.
