## What is CVE-2010-20108?

CVE-2010-20108 is a high-severity memory corruption vulnerability in FTPPad FTP Client, published on 21 Aug 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

FTPPad <= 1.2.0 contains a stack-based buffer overflow vulnerability in its FTP directory listing parser. When the client connects to an FTP server and receives a crafted response to a LIST command containing an excessively long directory and filename, the application fails to properly validate input length. This results in a buffer overflow that overwrites the saved Extended Instruction Pointer (EIP), allowing remote attackers to execute arbitrary code.

Weakness: CWE-121 (Stack-based Buffer Overflow)

What it is: CVE-2010-20108 is a high-severity memory corruption vulnerability in FTPPad FTP Client, published on 21 Aug 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2010-20108 exists.

Affected product: FTPPad FTP Client. 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.
