## What is CVE-2019-15266?

CVE-2019-15266 is a medium-severity path traversal vulnerability in Cisco Wireless Lan Controller Software, published on 16 Oct 2019. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A vulnerability in the CLI of Cisco Wireless LAN Controller (WLC) Software could allow an authenticated, local attacker to view system files that should be restricted. This vulnerability is due to improper sanitization of user-supplied input in command-line parameters that describe filenames. An attacker could exploit this vulnerability by using directory traversal techniques to submit a path to a desired file location. A successful exploit could allow the attacker to view system files that may contain sensitive information.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Check this codebase for CVE-2019-15266 and fix it if it is affected.

What it is: CVE-2019-15266 is a medium-severity path traversal vulnerability in Cisco Wireless Lan Controller Software, published on 16 Oct 2019. 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-2019-15266 in the wild and no public exploit code.

Affected product: Cisco Wireless Lan Controller Software. 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.
