## What is CVE-2023-23588?

CVE-2023-23588 is a medium-severity vulnerability in Siemens SIMATIC IPC1047, published on 11 Apr 2023. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A vulnerability has been identified in SIMATIC IPC1047 (All versions), SIMATIC IPC1047E (All versions with maxView Storage Manager < 4.09.00.25611 on Windows), SIMATIC IPC647D (All versions), SIMATIC IPC647E (All versions with maxView Storage Manager < 4.09.00.25611 on Windows), SIMATIC IPC847D (All versions), SIMATIC IPC847E (All versions with maxView Storage Manager < 4.09.00.25611 on Windows).

Check this codebase for CVE-2023-23588 and fix it if it is affected.

What it is: CVE-2023-23588 is a medium-severity vulnerability in Siemens SIMATIC IPC1047, published on 11 Apr 2023. 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-2023-23588 in the wild and no public exploit code.

Affected product: Siemens SIMATIC IPC1047. 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.
