## What is CVE-2014-125125?

CVE-2014-125125 is a high-severity path traversal vulnerability in A10 Networks AX Series Loadbalancer, published on 31 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A path traversal vulnerability exists in A10 Networks AX Loadbalancer versions 2.6.1-GR1-P5, 2.7.0, and earlier. The vulnerability resides in the handling of the filename parameter in the /xml/downloads endpoint, which fails to properly sanitize user input. An unauthenticated attacker can exploit this flaw by sending crafted HTTP requests containing directory traversal sequences to read arbitrary files outside the intended directory. The files returned by the vulnerable endpoint are deleted from the system after retrieval. This can lead to unauthorized disclosure of sensitive information such as SSL certificates and private keys, as well as unintended file deletion.

Weakness: CWE-706 (Use of Incorrectly-Resolved Name or Reference), CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Affected product: A10 Networks AX Series Loadbalancer. 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.
