CVE-2024-27905 refers to a critical vulnerability that exposes sensitive information to unauthorized actors in Apache Aurora projects. This vulnerability can be potentially exploited by malicious attackers to construct a valid authentication cookie and eventually achieve remote code execution by combining it with vulnerabilities in other components. It is essential to note that this vulnerability affects products that are no longer supported or maintained.

Background

Apache Aurora is an open-source service scheduler platform designed to efficiently manage and distribute resources across a large number of machines, primarily focusing on long-running services. Developed by Apache Software Foundation, the project has been deprecated and no longer receives active support or updates from the maintainers.

Vulnerability Details

The vulnerability, CVE-2024-27905, is an exposure of sensitive information to an unauthorized actor in Apache Aurora. A specific endpoint within this platform exposes internal system data to unauthenticated users. This exposed information can effectively serve as a "padding oracle" for attackers, allowing them to create valid authentication cookies.

The potential exploit of this vulnerability can lead to an anonymous attacker executing malicious code remotely on Apache Aurora instances by leveraging other component vulnerabilities.

Code Snippet

An example of creating a valid authentication cookie based on the information exposed through the vulnerable endpoint could be:

import requests

(url, vulnerable_endpoint) = (
    "http://target-aurora-instance:8081";,
    "/api/v1/internal"
)

response = requests.get(f"{url}/{vulnerable_endpoint}")

if response.status_code == 200:
    exposed_information = response.json()
    # Use the exposed information to generate a valid authentication cookie
    crafted_auth_cookie = generate_auth_cookie(exposed_information)
else:
    raise RuntimeError(f"Failed to access vulnerable endpoint {vulnerable_endpoint}")

Since the Apache Aurora project is now deprecated and no longer supported, the maintainers will not release a version that addresses this specific vulnerability. Users are strongly advised to consider alternative solutions or restrict access to their Aurora instances to only trusted users.

Conclusion

CVE-2024-27905 serves as a reminder of the potential consequences of running unsupported software, especially software that manages sensitive information and critical infrastructure. Staying informed about the status of the software you rely on and updating to newer, supported alternatives will help mitigate vulnerabilities and protect your systems from exploitation by malicious actors.
