## What is CVE-2024-56733?

CVE-2024-56733 is a medium-severity authentication bypass vulnerability in pglombardo PasswordPusher, published on 30 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Password Pusher is an open source application to communicate sensitive information over the web. A vulnerability has been reported in versions 1.50.3 and prior where an attacker can copy the session cookie before a user logs out, potentially allowing session hijacking. Although the session token is replaced and invalidated upon logout, if an attacker manages to capture the session cookie before this process, they can use the token to gain unauthorized access to the user's session until the token expires or is manually cleared. This vulnerability hinges on the attacker's ability to access the session cookie during an active session, either through a man-in-the-middle attack, by exploiting another vulnerability like XSS, or via direct access to the victim's device. Although there is no direct resolution to this vulnerability, it is recommended to always use the latest version of Password Pusher to best mitigate risk. If self-hosting, ensure Password Pusher is hosted exclusively over SSL connections to encrypt traffic and prevent session cookies from being intercepted in transit. Additionally, implement best practices in local security to safeguard user systems, browsers, and data against unauthorized access.

Weakness: CWE-384 (Session Fixation)

Affected packages and fixed versions:
- pwpush (RubyGems): affected all versions up to 1.50.3; no fix listed
- pwpush (RubyGems): affected all versions up to 1.50.3; no fix listed

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.
