## What is CVE-2022-27582?

CVE-2022-27582 is a critical authentication bypass vulnerability in SICK SIM4000 (PPC), published on 1 Nov 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Password recovery vulnerability in SICK SIM4000 (PPC) Partnumber 1078787 allows an unprivileged remote attacker to gain access to the userlevel defined as RecoverableUserLevel by invocating the password recovery mechanism method. This leads to an increase in their privileges on the system and thereby affecting the confidentiality integrity and availability of the system. An attacker can expect repeatable success by exploiting the vulnerability. The firmware versions <=1.10.1 allow to optionally disable device configuration over the network interfaces. Please make sure that you apply general security practices when operating the SIM4000. A fix is planned but not yet scheduled.

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

Check this codebase for CVE-2022-27582 and fix it if it is affected.

What it is: CVE-2022-27582 is a critical authentication bypass vulnerability in SICK SIM4000 (PPC), published on 1 Nov 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-2022-27582 in the wild and no public exploit code.

Affected product: SICK SIM4000 (PPC). 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.
