A flaw was found in the skupper console, a read-only interface that renders cluster network, traffic details, and metrics for a network application that a user sets up across a hybrid multi-cloud environment. When the default authentication method is used, a random password is generated for the "admin" user and is persisted in either a Kubernetes secret or a podman volume in a plaintext file. This authentication method can be manipulated by an attacker, leading to the reading of any user-readable file in the container filesystem, directly impacting data confidentiality. Additionally, the attacker may induce skupper to read extremely large files into memory, resulting in resource exhaustion and a denial of service attack.

When a skupper site is initialized with the console enabled and the default authentication method selected, it configures the skupper console with a flawed basic auth implementation. This implementation can be manipulated by an actor with network access to bypass authentication or to DOS the skupper console - potentially impacting the functionality of the skupper installation.

Security Fix(es): python: Path traversal on tempfile.TemporaryDirectory (CVE-2023-6597) python: The zipfile module is vulnerable to zip-bombs leading to denial of service (CVE-2024-0450) skupper: potential authentication bypass to skupper console via forged cookies (CVE-2024-6535) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
