## What is CVE-2017-6784?

CVE-2017-6784 is a medium-severity vulnerability in Cisco Systems, Inc. RV340, RV345, and RV345P Dual WAN Gigabit VPN Routers, published on 17 Aug 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A vulnerability in the web interface of the Cisco RV340, RV345, and RV345P Dual WAN Gigabit VPN Routers could allow an unauthenticated, remote attacker to access sensitive data. The attacker could use this information to conduct additional reconnaissance attacks. The vulnerability is due to Cisco WebEx Meetings not sufficiently protecting sensitive data when responding to an HTTP request to the web interface. An attacker could exploit the vulnerability by attempting to use the HTTP protocol and looking at the data in the HTTP responses from the Cisco WebEx Meetings Server. An exploit could allow the attacker to find sensitive information about the application. Cisco Bug IDs: CSCve37988. Known Affected Releases: firmware 1.0.0.30, 1.0.0.33, 1.0.1.9, 1.0.1.16.

Weakness: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)

What it is: CVE-2017-6784 is a medium-severity vulnerability in Cisco Systems, Inc. RV340, RV345, and RV345P Dual WAN Gigabit VPN Routers, published on 17 Aug 2017. 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-2017-6784 in the wild and no public exploit code.

Affected product: Cisco Systems, Inc. RV340, RV345, and RV345P Dual WAN Gigabit VPN Routers. 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.
