## What is CVE-2020-15643?

CVE-2020-15643 is a high-severity path traversal vulnerability in Marvell QConvergeConsole, published on 25 Aug 2020. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Marvell QConvergeConsole 5.5.0.64. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the saveAsText method of the GWTTestServiceImpl class. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-10549.

Check this codebase for CVE-2020-15643 and fix it if it is affected.

What it is: CVE-2020-15643 is a high-severity path traversal vulnerability in Marvell QConvergeConsole, published on 25 Aug 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-2020-15643 in the wild and no public exploit code.

Affected product: Marvell QConvergeConsole. 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.
