# CVE-2010-0928: Weak cryptography in n/a

> Physically proximate attackers can recover private keys from OpenSSL on specific FPGA hardware via voltage fault injection attacks.

- **Severity:** Medium 4.0 (`AV:L/AC:H/Au:N/C:C/I:N/A:N`)
- **Exploited in the wild:** Not known
- **Login needed:** Not needed
- **Attackable:** Local or same network only
- **Victim action needed:** Not needed
- **Fix available:** No
- **Published:** 5 Mar 2010
- **Updated:** 7 Aug 2024
- **Also known as:** GHSA-h3c3-6h4v-h278

## What is CVE-2010-0928?

CVE-2010-0928 is a medium-severity vulnerability in Openssl Openssl, published on 5 Mar 2010. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

OpenSSL 0.9.8i on the Gaisler Research LEON3 SoC on the Xilinx Virtex-II Pro FPGA uses a Fixed Width Exponentiation (FWE) algorithm for certain signature calculations, and does not verify the signature before providing it to a caller, which makes it easier for physically proximate attackers to determine the private key via a modified supply voltage for the microprocessor, related to a "fault-based attack."

Weakness: CWE-310

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2010-0928 and fix it if it is affected.

What it is: CVE-2010-0928 is a medium-severity vulnerability in Openssl Openssl, published on 5 Mar 2010. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2010-0928 in the wild and no public exploit code.

Affected product: Openssl Openssl. 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.
