## What is CVE-2022-38138?

CVE-2022-38138 is a high-severity vulnerability in Triangle Microworks Library: IEC 60870-6 (ICCP/Tase.2), published on 11 Oct 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The Triangle Microworks IEC 61850 Library (Any client or server using the C language library with a version number of 11.2.0 or earlier and any client or server using the C++, C#, or Java language library with a version number of 5.0.1 or earlier) and 60870-6 (ICCP/TASE.2) Library (Any client or server using a C++ language library with a version number of 4.4.3 or earlier) are vulnerable to access given to a small number of uninitialized pointers within their code. This could allow an attacker to target any client or server using the affected libraries to cause a denial-of-service condition.

Weakness: CWE-824 (Access of Uninitialized Pointer)

What it is: CVE-2022-38138 is a high-severity vulnerability in Triangle Microworks Library: IEC 60870-6 (ICCP/Tase.2), published on 11 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-2022-38138 in the wild and no public exploit code.

Affected product: Triangle Microworks Library: IEC 60870-6 (ICCP/Tase.2). 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.
