## What is CVE-2022-40202?

CVE-2022-40202 is a critical unsafe deserialization vulnerability in Delta Electronics InfraSuite Device Master, published on 31 Oct 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The database backup function in Delta Electronics InfraSuite Device Master Versions 00.00.01a and prior lacks proper authentication. An attacker could provide malicious serialized objects which, when deserialized, could activate an opcode for a backup scheduling function without authentication. This function allows the user to designate all function arguments and the file to be executed. This could allow the attacker to start any new process and achieve remote code execution.

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

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2022-40202 and fix it if it is affected.

What it is: CVE-2022-40202 is a critical unsafe deserialization vulnerability in Delta Electronics InfraSuite Device Master, published on 31 Oct 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-2022-40202 in the wild and no public exploit code.

Affected product: Delta Electronics InfraSuite Device Master. 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.
