## What is CVE-2018-0343?

CVE-2018-0343 is a high-severity missing authorization vulnerability in Cisco SD-WAN Solution unknown, published on 18 Jul 2018. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

A vulnerability in the configuration and management service of the Cisco SD-WAN Solution could allow an authenticated, remote attacker to execute arbitrary code with vmanage user privileges or cause a denial of service (DoS) condition on an affected system. The vulnerability is due to insufficient access restrictions to the HTTP management interface of the affected solution. An attacker could exploit this vulnerability by sending a malicious HTTP request to the affected management service through an authenticated device. A successful exploit could allow the attacker to execute arbitrary code with vmanage user privileges or stop HTTP services on an affected system. This vulnerability affects the following Cisco products if they are running a release of the Cisco SD-WAN Solution prior to Release 18.3.0: vBond Orchestrator Software, vEdge 100 Series Routers, vEdge 1000 Series Routers, vEdge 2000 Series Routers, vEdge 5000 Series Routers, vEdge Cloud Router Platform, vManage Network Management Software, vSmart Controller Software. Cisco Bug IDs: CSCvi69976.

Check this codebase for CVE-2018-0343 and fix it if it is affected.

What it is: CVE-2018-0343 is a high-severity missing authorization vulnerability in Cisco SD-WAN Solution unknown, published on 18 Jul 2018. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2018-0343 in the wild and no public exploit code.

Affected product: Cisco SD-WAN Solution unknown. 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.
