The Azure CycleCloud product is missing security updates. It is, therefore, affected by the following vulnerabilities:

  - A remote code execution vulnerability exists due to a disclosure of the storage credentials. An     authenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands     with root privileges. (CVE-2024-38195)

  - A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt     captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or     sensitive data. (CVE-2023-50782)

  - A denial of service (DoS) vulnerability exists in python-cryptography due to the     pkcs12.serialize_key_and_certificates function. An unauthenticated, remote attacker can exploit this     issue, via specially crafted certificate, to cause the process to stop responding. (CVE-2024-26130)

  - A denial of service (DoS) vulnerability exists in ws, an open source WebSocket client and server for     Node.js, due to the handling of headers. An unauthenticated, remote attacker can exploit this issue, via     specially crafted request, to cause the application to stop responding. (CVE-2024-37890)

    Hubert Kario discovered that python-cryptography incorrectly handled

    errors returned by the OpenSSL API when processing incorrect padding in

    RSA PKCS#1 v1.5. A remote attacker could possibly use this issue to expose

    confidential or sensitive information. (CVE-2023-50782)

    It was discovered that python-cryptography incorrectly handled memory

    operations when processing mismatched PKCS#12 keys. A remote attacker could

    possibly use this issue to cause python-cryptography to crash, leading to a denial of service. This issue     only affected Ubuntu 23.10. (CVE-2024-26130)
