# CVE-2017-17485: jackson-databind vulnerable to remote code execution due to incorrect deserialization and blocklist bypass

> Attackers can achieve remote code execution by sending malicious JSON to the ObjectMapper, bypassing blacklist protections in the Jackson library.

- **Severity:** Critical 9.8 (`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`)
- **Exploited in the wild:** Not known

## What is CVE-2017-17485?

CVE-2017-17485 is a critical unsafe deserialization vulnerability in Debian Debian Linux, published on 10 Jan 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

FasterXML jackson-databind through 2.8.10 and 2.9.x through 2.9.3 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 deserialization flaw. This is exploitable by sending maliciously crafted JSON input to the readValue method of the ObjectMapper, bypassing a blacklist that is ineffective if the Spring libraries are available in the classpath.

Weakness: CWE-502 (Deserialization of Untrusted Data)

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.
