## What is CVE-2011-10032?

CVE-2011-10032 is a critical memory corruption vulnerability in Sunway ForceControl, published on 30 Aug 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Sunway ForceControl version 6.1 SP3 and earlier contains a stack-based buffer overflow vulnerability in the SNMP NetDBServer service, which listens on TCP port 2001. The flaw is triggered when the service receives a specially crafted packet using opcode 0x57 with an overly long payload. Due to improper bounds checking during packet parsing, attacker-controlled data overwrites the Structured Exception Handler (SEH), allowing arbitrary code execution in the context of the service. This vulnerability can be exploited remotely without authentication and may lead to full system compromise on affected Windows hosts.

Weakness: CWE-121 (Stack-based Buffer Overflow)

```text
Check this codebase for CVE-2011-10032 and fix it if it is affected.

What it is: CVE-2011-10032 is a critical memory corruption vulnerability in Sunway ForceControl, published on 30 Aug 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2011-10032 exists.

Affected product: Sunway ForceControl. 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.
