## What is CVE-2017-6617?

CVE-2017-6617 is a medium-severity authentication bypass vulnerability in Cisco Integrated Management Controller, published on 20 Apr 2017. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

A vulnerability in the session identification management functionality of the web-based GUI of Cisco Integrated Management Controller (IMC) 3.0(1c) could allow an unauthenticated, remote attacker to hijack a valid user session on an affected system. The vulnerability exists because the affected software does not assign a new session identifier to a user session when a user authenticates to the web-based GUI. An attacker could exploit this vulnerability by using a hijacked session identifier to connect to the software through the web-based GUI. A successful exploit could allow the attacker to hijack an authenticated user's browser session on the affected system. Cisco Bug IDs: CSCvd14583.

Weakness: CWE-287 (Improper Authentication)

Check this codebase for CVE-2017-6617 and fix it if it is affected.

What it is: CVE-2017-6617 is a medium-severity authentication bypass vulnerability in Cisco Integrated Management Controller, published on 20 Apr 2017. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2017-6617 in the wild and no public exploit code.

Affected product: Cisco Integrated Management Controller. 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.
