## What is CVE-2017-12266?

CVE-2017-12266 is a medium-severity path traversal vulnerability in Cisco Meeting App, published on 5 Oct 2017. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A vulnerability in the routine that loads DLL files in Cisco Meeting App for Windows could allow an authenticated, local attacker to run an executable file with privileges equivalent to those of Cisco Meeting App. The vulnerability is due to incomplete input validation of the path name for DLL files before they are loaded. An attacker could exploit this vulnerability by installing a crafted DLL file in a specific system directory. A successful exploit could allow the attacker to execute commands on the underlying Microsoft Windows host with privileges equivalent to those of Cisco Meeting App. The attacker would need valid user credentials to exploit this vulnerability. Cisco Bug IDs: CSCvd77907.

Weakness: CWE-427 (Uncontrolled Search Path Element), CWE-264

Check this codebase for CVE-2017-12266 and fix it if it is affected.

What it is: CVE-2017-12266 is a medium-severity path traversal vulnerability in Cisco Meeting App, published on 5 Oct 2017. 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-2017-12266 in the wild and no public exploit code.

Affected product: Cisco Meeting App. 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.
