## What is CVE-2012-5383?

CVE-2012-5383 is a medium-severity vulnerability in Oracle Mysql, published on 11 Oct 2012. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Untrusted search path vulnerability in the installation functionality in Oracle MySQL 5.5.28, when installed in the top-level C:\ directory, might allow local users to gain privileges via a Trojan horse DLL in the "C:\MySQL\MySQL Server 5.5\bin" directory, which may be added to the PATH system environment variable by an administrator, as demonstrated by a Trojan horse wlbsctrl.dll file used by the "IKE and AuthIP IPsec Keying Modules" system service in Windows Vista SP1, Windows Server 2008 SP2, Windows 7 SP1, and Windows 8 Release Preview. NOTE: CVE disputes this issue because the unsafe PATH is established only by a separate administrative action that is not a default part of the MySQL installation

Check this codebase for CVE-2012-5383 and fix it if it is affected.

What it is: CVE-2012-5383 is a medium-severity vulnerability in Oracle Mysql, published on 11 Oct 2012. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2012-5383 exists.

Affected product: Oracle Mysql. 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.
