## What is CVE-2019-19988?

CVE-2019-19988 is a high-severity path traversal vulnerability in n/a, published on 26 Feb 2020. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

An issue was discovered in Selesta Visual Access Manager (VAM) 4.15.0 through 4.29. A user with valid credentials is able to create and write XML files on the filesystem via /common/vam_editXml.php in the web interface. The vulnerable PHP page checks none of these: the parameter that identifies the file name to be created, the destination path, or the extension. Thus, an attacker can manipulate the file name to create any type of file within the filesystem with arbitrary content.

Weakness: CWE-787 (Out-of-bounds Write)

Check this codebase for CVE-2019-19988 and fix it if it is affected.

What it is: CVE-2019-19988 is a high-severity path traversal vulnerability in n/a, published on 26 Feb 2020. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2019-19988 in the wild and no public exploit code.

Affected product: n/a. 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.
