.NET Core Remote Code Execution Vulnerability

An update of the dotnet package has been released.

The 8.4.0 versions of MySQL Connectors installed on the remote host are affected by multiple vulnerabilities as referenced in the July 2024 CPU advisory.

  - Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/Net (.NET Core)).
    Supported versions that are affected are 8.4.0 and prior. Difficult to exploit vulnerability allows     unauthenticated attacker with network access via multiple protocols to compromise MySQL Connectors.
    Successful attacks of this vulnerability can result in takeover of MySQL Connectors. (CVE-2021-24112)

  - Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/Python). Supported     versions that are affected are 8.4.0 and prior. Easily exploitable vulnerability allows low privileged     attacker with network access via multiple protocols to compromise MySQL Connectors. Successful attacks of     this vulnerability can result in unauthorized update, insert or delete access to some of MySQL Connectors     accessible data as well as unauthorized read access to a subset of MySQL Connectors accessible data and     unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Connectors.
    (CVE-2024-21170)

The Microsoft .NET Core runtime installed on the remote macOS or Mac OS X host is missing a security update. It is, therefore, affected by multiple vulnerabilities:

  - A denial of service vulnerability exists in .NET Core when creating HTTPS web requests during X509     certificate chain building. An unauthenticated, remote attacker can exploit this to cause the application     to stop responding. (CVE-2021-1721)

  - A remote code execution vulnerability exists in .NET Core when parsing certain types of graphics files. An     unauthenticated, remote attacker can exploit this to execute arbitrary code. This vulnerability only     exists on systems running on macOS or Linux. (CVE-2021-24112)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
