## What is CVE-2017-7649?

CVE-2017-7649 is a critical authentication bypass vulnerability in Eclipse Kura Installer, published on 11 Sep 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The network enabled distribution of Kura before 2.1.0 takes control over the device's firewall setup but does not allow IPv6 firewall rules to be configured. Still the Equinox console port 5002 is left open, allowing to log into Kura without any user credentials over unencrypted telnet and executing commands using the Equinox "exec" command. As the process is running as "root" full control over the device can be acquired. IPv6 is also left in auto-configuration mode, accepting router advertisements automatically and assigns a MAC address based IPv6 address.

Weakness: CWE-287 (Improper Authentication)

Check this codebase for CVE-2017-7649 and fix it if it is affected.

What it is: CVE-2017-7649 is a critical authentication bypass vulnerability in Eclipse Kura Installer, published on 11 Sep 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-2017-7649 in the wild and no public exploit code.

Affected product: Eclipse Kura Installer. 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.
