## What is CVE-2022-48307?

CVE-2022-48307 is a medium-severity vulnerability in Palantir Foundry Magritte, published on 16 Feb 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

It was discovered that the Magritte-ftp was not verifying hostnames in TLS certificates due to a misuse of the javax.net.ssl.SSLSocketFactory API. A malicious attacker in a privileged network position could abuse this to perform a man-in-the-middle attack. A successful man-in-the-middle attack would allow them to intercept, read, or modify network communications to and from the affected service. In the case of a successful man in the middle attack on magritte-ftp, an attacker would be able to read and modify network traffic such as authentication tokens or raw data entering a Palantir Foundry stack.

Weakness: CWE-295 (Improper Certificate Validation), CWE-297 (Improper Validation of Certificate with Host Mismatch)

What it is: CVE-2022-48307 is a medium-severity vulnerability in Palantir Foundry Magritte, published on 16 Feb 2023. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2022-48307 in the wild and no public exploit code.

Affected product: Palantir Foundry Magritte. 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.
