## What is CVE-2022-35572?

CVE-2022-35572 is a high-severity missing authorization vulnerability in n/a, published on 12 Sep 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

On Linksys E5350 WiFi Router with firmware version 1.0.00.037 and lower, (and potentially other vendors/devices due to code reuse), the /SysInfo.htm URI does not require a session ID. This web page calls a show_sysinfo function which retrieves WPA passwords, SSIDs, MAC Addresses, serial numbers, WPS Pins, and hardware/firmware versions, and prints this information into the web page. This web page is visible when remote management is enabled. A user who has access to the web interface of the device can extract these secrets. If the device has remote management enabled and is connected directly to the internet, this vulnerability is exploitable over the internet without interaction.

Weakness: CWE-306 (Missing Authentication for Critical Functionality)

Check this codebase for CVE-2022-35572 and fix it if it is affected.

What it is: CVE-2022-35572 is a high-severity missing authorization vulnerability in n/a, published on 12 Sep 2022. 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-2022-35572 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.
