## What is CVE-2017-1000085?

CVE-2017-1000085 is a medium-severity vulnerability in n/a, published on 4 Oct 2017. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Subversion Plugin connects to a user-specified Subversion repository as part of form validation (e.g. to retrieve a list of tags). This functionality improperly checked permissions, allowing any user with Item/Build permission (but not Item/Configure) to connect to any web server or Subversion server and send credentials with a known ID, thereby possibly capturing them. Additionally, this functionality did not require POST requests be used, thereby allowing the above to be performed without direct access to Jenkins via Cross-Site Request Forgery attacks.

Weakness: CWE-352 (Cross-Site Request Forgery)

Check this codebase for CVE-2017-1000085 and fix it if it is affected.

What it is: CVE-2017-1000085 is a medium-severity vulnerability in n/a, published on 4 Oct 2017. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2017-1000085 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.jenkins-ci.plugins:subversion (Maven): affected all versions; fixed in 2.9
- org.jenkins-ci.plugins:subversion (Maven): affected all versions; fixed in 2.9

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.
