## What is CVE-2009-4269?

CVE-2009-4269 is a low-severity vulnerability in n/a, published on 16 Aug 2010. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The password hash generation algorithm in the BUILTIN authentication functionality for Apache Derby before 10.6.1.0 performs a transformation that reduces the size of the set of inputs to SHA-1, which produces a small search space that makes it easier for local and possibly remote attackers to crack passwords by generating hash collisions, related to password substitution.

Weakness: CWE-310

Check this codebase for CVE-2009-4269 and fix it if it is affected.

What it is: CVE-2009-4269 is a low-severity vulnerability in n/a, published on 16 Aug 2010. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2009-4269 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.apache.derby:derby (Maven): affected all versions; fixed in 10.6.1.0
- org.apache.derby:derby (Maven): affected all versions; fixed in 10.6.1.0

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.
