## What is CVE-2018-17022?

CVE-2018-17022 is a high-severity memory corruption vulnerability in n/a, published on 13 Sep 2018. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

Stack-based buffer overflow on the ASUS GT-AC5300 router through 3.0.0.4.384_32738 allows remote attackers to cause a denial of service (device crash) or possibly have unspecified other impact by setting a long sh_path0 value and then sending an appGet.cgi?hook=select_list("Storage_x_SharedPath") request, because ej_select_list in router/httpd/web.c uses strcpy.

Weakness: CWE-787 (Out-of-bounds Write)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2018-17022 and fix it if it is affected.

What it is: CVE-2018-17022 is a high-severity memory corruption vulnerability in n/a, published on 13 Sep 2018. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2018-17022 in the wild and no public exploit code.

Affected product: n/a. 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.
