CVE-2023-1934 is a critical SQL injection vulnerability in SDG Technologies PnPSCADA, published on 12 May 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The PnPSCADA system, a product of SDG Technologies CC, is afflicted by a critical unauthenticated error-based PostgreSQL Injection vulnerability. Present within the hitlogcsv.jsp endpoint, this security flaw permits unauthenticated attackers to engage with the underlying database seamlessly and passively. Consequently, malicious actors could gain access to vital information, such as Industrial Control System (ICS) and OT data, alongside other sensitive records like SMS and SMS Logs. The unauthorized database access exposes compromised systems to potential manipulation or breach of essential infrastructure data, highlighting the severity of this vulnerability.

What it is: CVE-2023-1934 is a critical SQL injection vulnerability in SDG Technologies PnPSCADA, published on 12 May 2023. 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-2023-1934 in the wild and no public exploit code.

Affected product: SDG Technologies PnPSCADA. 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.
