### Impact On instances where `Extension Repository Application` is installed, any user can execute any code requiring `programming` rights on the server. In order to reproduce on an instance, as a normal user without `script` nor `programming` rights, go to your profile and add an object of type `ExtensionCode.ExtensionClass`. Set the description to `{{async}}{{groovy}}println("Hello from Description"){{/groovy}}{{/async}}` and press `Save and View`. If the description displays as `Hello from Description` without any error, then the instance is vulnerable. ### Patches This vulnerability has been fixed in XWiki 15.10.9 and 16.3.0. ### Workarounds Since `Extension Repository Application` is not mandatory, it can be safely disabled on instances that do not use it. It is also possible to manually apply [this patch](https://github.com/xwiki/xwiki-platform/commit/8659f17d500522bf33595e402391592a35a162e8#diff-9b6f9e853f23d76611967737f8c4072ffceaba4c006ca5a5e65b66d988dc084a) to the page `Ex...

### Impact When calling the extended toHTMLEx method, it is possible to execute arbitrary JavaScript code. ### Patches The supplied patch resolves this vulnerability for SimpleXLSX. Use 1.1.12 ### Workarounds Don't use direct publication via toHTMLEx *** This vulnerability was discovered by Aleksey Solovev (Positive Technologies)

In the context of using MD5 to generate filenames for cache keys, there are significant collision hazards that need to be considered. MD5, or Message Digest Algorithm 5, is a widely known cryptographic hash function that produces a 128-bit hash value. However, MD5 is no longer considered secure against well-funded opponents due to its vulnerability to collision attacks. ### Understanding Collisions A collision in hashing occurs when two different inputs produce the same hash output. For MD5, this means that it is theoretically possible, and even practical, to find two distinct cache keys that result in the same MD5 hash. This vulnerability has been well-documented and exploited in various security contexts. ### Implications for Cache Systems In a cache system where filenames are derived from the MD5 hash of cache keys, a collision could lead to several critical issues: Data Integrity Risks: If two different keys collide, they will map to the same filename. This could result in data ...

### Summary _Short summary of the problem. Make the impact and severity as clear as possible. For example: An unsafe deserialization vulnerability allows any unauthenticated user to execute arbitrary code on the server._ There is a potential XXE(XML External Entity Injection) vulnerability when http4k handling malicious XML contents within requests, which might allow attackers to read local sensitive information on server, trigger Server-side Request Forgery and even execute code under some circumstances. ### Details _Give all details on the vulnerability. Pointing to the incriminated source code is very helpful for the maintainer._ https://github.com/http4k/http4k/blob/25696dff2d90206cc1da42f42a1a8dbcdbcdf18c/core/format/xml/src/main/kotlin/org/http4k/format/Xml.kt#L42-L46 XML contents is parsed with DocumentBuilder without security settings on or external entity enabled ### PoC _Complete instructions, including specific configuration details, to reproduce the vulnerability._ #### ...

### Impact 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. ### Patches This has been patched in XWiki 15.10.9 and 16.3.0. ### Workarounds If you have subwikis where the Job Scheduler is enabled, you can edit the objects on `Scheduler.WebPreferences` to match https://github.com/xwiki/xwiki-platform/commit/54bcc5a7a2e440cc591b91eece9c13dc0c487331#diff-8e274bd0065e319a34090339de6dfe56193144d15fd71c52c1be7272254728b4. ### References * https://jira.xwiki.org/browse/XWIKI-21663 * https://github.com/xwiki/xwiki-platform/commit/54bcc5a7a2e440cc591b91eece9c13dc0c487331 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) *...

### Impact 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. To reproduce on a instance, as a connected user without script nor programming rights, go to your user profile and add an object of type `XWiki.WikiMacroClass`. Set "Macro Id", "Macro Name" and "Macro Code" to any value, "Macro Visibility" to `Current User` and "Macro Description" to `{{async}}{{groovy}}println("Hello from User macro!"){{/groovy}}{{/async}}`. Save the page, then go to `<host>/xwiki/bin/view/XWiki/XWikiSyntaxMacrosList`. If the description of your new macro reads "Hello from User macro!", then your instance is vulnerable. ### Patches This vulnerability has been fixed in XWiki 15.10.11, 16.4.1 and 16.5.0. ### Workarounds It is possible to manually apply [this patch](https://github.com/xwiki/xwiki-platform/commit/40e1afe001d61eafdf13f36...

### Impact 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. To reproduce on a instance, as a user with script rights, edit your user profile and add an object of type `XWiki.ConfigurableClass` ("Custom configurable sections"). Set "Display in section" and "Display in category" to `other`, "Scope" to `Wiki and all spaces` and "Heading" to: ``` #set($codeToExecute = 'Test') #set($codeToExecuteResult = '{{async}}{{groovy}}services.logging.getLogger("attacker").error("Attack from Heading succeeded!"){{/groovy}}{{/async}}') ``` Save the page and view it, then add `?sheet=XWiki.AdminSheet&viewer=content&section=other` to the URL. If the logs contain "attacker - Attack from Heading succeeded!", then the instance is vulnerable. ### Patches This has been patched in XWiki 15.10.9 and 16.3.0. ### Workarounds We're...
