Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Microsoft.IdentityModel.Protocols.SignedHttpRequest, software state validation or input boundaries are circumvented during processing.

"details" : "### Impact\n_What kind of vulnerability is it? Who is impacted?_\nAnyone 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. \n\n### Patches\n_Has the problem been patched? What versions should users upgrade to?_\nThe 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, if using Microsoft.IdentityModel.Protocols.SignedHttpRequest.\n\n### Workarounds\n_Is there a way for users to fix or remediate the vulnerability without upgrading?_\nNo, users must upgrade.\n\n### References\n_Are there any links users can visit to find out more?_\nhttps://aka.ms/IdentityModel/Jan2024/jku",
