## What is CVE-2014-0773?

CVE-2014-0773 is a high-severity command injection vulnerability in Advantech WebAccess, published on 12 Apr 2014. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

The BWOCXRUN.BwocxrunCtrl.1 control contains a method named 
“CreateProcess.” This method contains validation to ensure an attacker 
cannot run arbitrary command lines. After validation, the values 
supplied in the HTML are passed to the Windows CreateProcessA API.

The validation can be bypassed allowing for running arbitrary command
 lines. The command line can specify running remote files (example: UNC 
command line).

A function exists at offset 100019B0 of bwocxrun.ocx. Inside this 
function, there are 3 calls to strstr to check the contents of the user 
specified command line. If “\setup.exe,” “\bwvbprt.exe,” or 
“\bwvbprtl.exe” are contained in the command line (strstr returns 
nonzero value), the command line passes validation and is then passed to
 CreateProcessA.

Weakness: CWE-77 (Improper Neutralization of Special Elements used in a Command)

```text
Check this codebase for CVE-2014-0773 and fix it if it is affected.

What it is: CVE-2014-0773 is a high-severity command injection vulnerability in Advantech WebAccess, published on 12 Apr 2014. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2014-0773 in the wild and no public exploit code.

Affected product: Advantech WebAccess. 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.
