## What is CVE-2022-2758?

CVE-2022-2758 is a medium-severity vulnerability in LS Industrial Systems (LSIS) Co. Ltd LS Electric PLC: XGB-XBCH, published on 31 Aug 2022. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Passwords are not adequately encrypted during the communication process between all versions of LS Industrial Systems (LSIS) Co. Ltd LS Electric XG5000 software prior to V4.0 and LS Electric PLCs: all versions of XGK-CPUU/H/A/S/E prior to V3.50, all versions of XGI-CPUU/UD/H/S/E prior to V3.20, all versions of XGR-CPUH prior to V1.80, all versions of XGB-XBMS prior to V3.00, all versions of XGB-XBCH prior to V1.90, and all versions of XGB-XECH prior to V1.30. This would allow an attacker to identify and decrypt the password of the affected PLCs by sniffing the PLC’s communication traffic.

Weakness: CWE-326 (Inadequate Encryption Strength)

What it is: CVE-2022-2758 is a medium-severity vulnerability in LS Industrial Systems (LSIS) Co. Ltd LS Electric PLC: XGB-XBCH, published on 31 Aug 2022. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2022-2758 in the wild and no public exploit code.

Affected product: LS Industrial Systems (LSIS) Co. Ltd LS Electric PLC: XGB-XBCH. 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.
