# CVE-2023-40573: XWiki Platform's Groovy jobs check the wrong author, allowing remote code execution > Attackers with edit rights can achieve remote code execution via Groovy scheduled jobs due to incorrect author verification and CSRF. - **Severity:** Critical 9.1 (`CVSS:3.1/AV:N/AC:L/PR:L/UI:R/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:** A user has to click or open something - **Fix available:** Yes - **Published:** 24 Aug 2023 - **Updated:** 3 Oct 2024 - **Also known as:** GHSA-8xhr-x3v8-rghj ## What is CVE-2023-40573? CVE-2023-40573 is a critical code injection vulnerability in Xwiki Xwiki, published on 24 Aug 2023. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link. ### Official description XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. XWiki supports scheduled jobs that contain Groovy scripts. Currently, the job checks the content author of the job for programming right. However, modifying or adding a job script to a document doesn't modify the content author. Together with a CSRF vulnerability in the job scheduler, this can be exploited for remote code execution by an attacker with edit right on the wiki. If the attack is successful, an error log entry with "Job content executed" will be produced. This vulnerability has been patched in XWiki 14.10.9 and 15.4RC1.

Affected packages and fixed versions: - org.xwiki.platform:xwiki-platform-scheduler-api (Maven): affected all versions; fixed in 14.10.9 - org.xwiki.platform:xwiki-platform-scheduler-api (Maven): affected all versions; fixed in 14.10.9 - org.xwiki.platform:xwiki-platform-scheduler-api (Maven): affected from 15.0-rc-1; fixed in 15.4-rc-1 - org.xwiki.platform:xwiki-platform-scheduler-api (Maven): affected from 15.0-rc-1; fixed in 15.4-rc-1 - com.xpn.xwiki.platform.plugins:xwiki-plugin-scheduler (Maven): affected from 1.3; no fix listed - com.xpn.xwiki.platform.plugins:xwiki-plugin-scheduler (Maven): affected from 1.3; no fix listed Task: 1. 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.
