# CVE-2023-37909: Privilege escalation (PR)/remote code execution from account through Menu.UIExtensionSheet > Authenticated users can execute arbitrary scripts via profile editing, leading to remote code execution and full wiki access. - **Severity:** Critical 10.0 (`CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 25 Oct 2023 - **Updated:** 17 Sep 2024 - **Also known as:** GHSA-v2rr-xw95-wcjx ## What is CVE-2023-37909? CVE-2023-37909 is a critical code injection vulnerability in Xwiki Xwiki, published on 25 Oct 2023. Any signed-in user can exploit it over the network, with no action from the victim. ### Official description XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 5.1-rc-1 and prior to versions 14.10.8 and 15.3-rc-1, any user who can edit their own user profile can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. This has been patched in XWiki 14.10.8 and 15.3-rc-1 by adding proper escaping. As a workaround, the patch can be manually applied to the document `Menu.UIExtensionSheet`; only three lines need to be changed. Weakness: CWE-94 (Improper Control of Generation of Code), CWE-95 (Improper Neutralization of Directives in Dynamically Evaluated Code) ## Which versions are affected by CVE-2023-37909? 6 open source packages ship an affected version, including org.xwiki.platform:xwiki-platform-menu-ui and org.xwiki.platform:xwiki-platform-menu.

Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
