## What is CVE-2022-24045?

CVE-2022-24045 is a medium-severity vulnerability in Siemens Desigo DXR2, published on 10 May 2022. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

A vulnerability has been identified in Desigo DXR2 (All versions < V01.21.142.5-22), Desigo PXC3 (All versions < V01.21.142.4-18), Desigo PXC4 (All versions < V02.20.142.10-10884), Desigo PXC5 (All versions < V02.20.142.10-10884). The application, after a successful login, sets the session cookie on the browser via client-side JavaScript code, without applying any security attributes (such as “Secure”, “HttpOnly”, or “SameSite”). Any attempts to browse the application via unencrypted HTTP protocol would lead to the transmission of all his/her session cookies in plaintext through the network. An attacker could then be able to sniff the network and capture sensitive information.

Weakness: CWE-311 (Missing Encryption of Sensitive Data), CWE-614 (Sensitive Cookie in HTTPS Session Without 'Secure' Attribute)

Check this codebase for CVE-2022-24045 and fix it if it is affected.

What it is: CVE-2022-24045 is a medium-severity vulnerability in Siemens Desigo DXR2, published on 10 May 2022. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2022-24045 in the wild and no public exploit code.

Affected product: Siemens Desigo DXR2. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
