## What is CVE-2019-17146?

CVE-2019-17146 is a high-severity memory corruption vulnerability in D-Link DCS-960L, published on 7 Jan 2020. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

This vulnerability allows remote attackers to execute arbitrary code on affected installations of D-Link DCS-960L v1.07.102. Authentication is not required to exploit this vulnerability. The specific flaw exists within the HNAP service, which listens on TCP port 80 by default. When parsing the SOAPAction request header, the process does not properly validate the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the admin user. Was ZDI-CAN-8458.

Weakness: CWE-306 (Missing Authentication for Critical Functionality), CWE-121 (Stack-based Buffer Overflow)

Check this codebase for CVE-2019-17146 and fix it if it is affected.

What it is: CVE-2019-17146 is a high-severity memory corruption vulnerability in D-Link DCS-960L, published on 7 Jan 2020. 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-2019-17146 in the wild and no public exploit code.

Affected product: D-Link DCS-960L. 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.
