## What is CVE-2022-2070?

CVE-2022-2070 is a critical memory corruption vulnerability in Grandstream GSD3710, published on 23 Sep 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

In Grandstream GSD3710 in its 1.0.11.13 version, it's possible to overflow the stack since it doesn't check the param length before using the sscanf instruction. Because of that, an attacker could create a socket and connect with a remote IP:port by opening a shell and getting full access to the system. The exploit affects daemons dbmng and logsrv that are running on ports 8000 and 8001 by default.

Weakness: CWE-787 (Out-of-bounds Write), CWE-121 (Stack-based Buffer Overflow)

Check this codebase for CVE-2022-2070 and fix it if it is affected.

What it is: CVE-2022-2070 is a critical memory corruption vulnerability in Grandstream GSD3710, published on 23 Sep 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

Affected product: Grandstream GSD3710. 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.
