      <title>CVE-2024-21643 — Microsoft.IdentityModel.Protocols.SignedHttpRequest remote code execution vulnerability</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2024-21643</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; AzureAD azure-activedirectory-identitymodel-extensions-for-dotnet&lt;/p&gt;
&lt;p&gt;IdentityModel Extensions for .NET provide assemblies for web developers that wish to use federated identity providers for establishing the caller&amp;#39;s identity. Anyone leveraging the `SignedHttpRequest`protocol or the `SignedHttpRequestValidator`is vulnerable. Microsoft.IdentityModel trusts the `jku`claim by default for the `SignedHttpRequest`protocol. This raises the possibility to make any remote or local `HTTP GET` request. The vulnerability has been fixed in Microsoft.IdentityModel.Protocols.SignedHttpRequest. Users should update all their Microsoft.IdentityModel versions to 7.1.2 (for 7x) or higher, 6.34.0 (for 6x) or higher.&lt;/p&gt;</description>
