CVE-2024-39917 is a high-severity vulnerability in neutrinolabs xrdp, published on 12 Jul 2024. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description xrdp is an open source RDP server. xrdp versions prior to 0.10.0 have a vulnerability that allows attackers to make an infinite number of login attempts. The number of max login attempts is supposed to be limited by a configuration parameter `MaxLoginRetry` in `/etc/xrdp/sesman.ini`. However, this mechanism was not effectively working. As a result, xrdp allows an infinite number of login attempts. Weakness: CWE-307 (Improper Restriction of Excessive Authentication Attempts) ## Which versions are affected by CVE-2024-39917?

What it is: CVE-2024-39917 is a high-severity vulnerability in neutrinolabs xrdp, published on 12 Jul 2024. 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-2024-39917 in the wild and no public exploit code. Affected product: neutrinolabs xrdp. 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.
