## What is CVE-2017-17174?

CVE-2017-17174 is a medium-severity vulnerability in Huawei Technologies Co., Ltd. RSE6500; SoftCo; VP9660; eSpace U1981, published on 31 Jul 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Some Huawei products RSE6500 V500R002C00; SoftCo V200R003C20SPCb00; VP9660 V600R006C10; eSpace U1981 V100R001C20; V200R003C20; V200R003C30; V200R003C50 have a weak algorithm vulnerability. To exploit the vulnerability, a remote, unauthenticated attacker has to capture TLS traffic between clients and the affected products. The attacker may launch the Bleichenbacher attack on RSA key exchange to decrypt the session key and the previously captured sessions by some cryptanalytic operations. Successful exploit may cause information leak.

Weakness: CWE-310

Check this codebase for CVE-2017-17174 and fix it if it is affected.

What it is: CVE-2017-17174 is a medium-severity vulnerability in Huawei Technologies Co., Ltd. RSE6500; SoftCo; VP9660; eSpace U1981, published on 31 Jul 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-17174 in the wild and no public exploit code.

Affected product: Huawei Technologies Co., Ltd. RSE6500; SoftCo; VP9660; eSpace U1981. 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.
