## What is CVE-2018-0342?

CVE-2018-0342 is a medium-severity memory corruption vulnerability in Cisco SD-WAN Solution unknown, published on 18 Jul 2018. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A vulnerability in the configuration and monitoring service of the Cisco SD-WAN Solution could allow an authenticated, local attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device. The vulnerability is due to incomplete bounds checks for data that is provided by the configuration and monitoring service of the affected solution. An attacker could exploit this vulnerability by sending malicious data to the vDaemon listening service on an affected device. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected device, which could allow the attacker to execute arbitrary code with root privileges on the device or cause the vDaemon listening service to reload and result in a DoS condition on the device. 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: CSCvi70003.

Weakness: CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2018-0342 and fix it if it is affected.

What it is: CVE-2018-0342 is a medium-severity memory corruption vulnerability in Cisco SD-WAN Solution unknown, published on 18 Jul 2018. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2018-0342 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.
