## What is CVE-2021-43960?

CVE-2021-43960 is a medium-severity cross-site scripting vulnerability in n/a, published on 12 Jan 2022. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.

### Official description

Lorensbergs Connect2 3.13.7647.20190 is affected by an XSS vulnerability. Exploitation requires administrator privileges and is performed through the Wizard editor of the application. The attack requires an administrator to go into the Wizard editor and enter an XSS payload within the Page title, Page Instructions, Text before, Text after, or Text on side box. Once this has been done, the administrator must click save and finally wait until any user of the application performs a booking for rental items in the booking area of the application, where the XSS triggers. NOTE: another perspective is that the administrator may require JavaScript to customize any aspect of the page rendering. There is no effective way for the product to defend users in the face of a malicious administrator

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

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.
