How to Fix GHSA-vx2x-9cff-fhjw

To remediate this vulnerability, upgrade all affected DSInternals.Common dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

DSInternals.Common fixed: 4.8 
Upgrade DSInternals.Common to 4.8
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for DSInternals.Common

How to Check if You Are Affected

To determine whether your application is affected by GHSA-vx2x-9cff-fhjw, inspect your project dependencies for DSInternals.Common:

inspect dependencies for DSInternals.Common

Analyze the terminal output to locate any version of DSInternals.Common in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.8), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In DSInternals.Common, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact A vulnerability exists in the `DSInternals.Common.Data.RoamedCredential.Save()` method, which incorrectly parses the `msPKIAccountCredentials` LDAP attribute values. As a consequence, a malicious actor would be able to modify the file system of the computer where an application using this function is executed with administrative privileges. A [similar security issue](https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-30170) used to be present in the Windows operating system, as DSInternals re-implements the Credential Roaming feature of Windows. ### Exploitability The vulnerability can be exploited under the following circumstances: - An attacker is able to modify the `msPKIAccountCredentials` attribute of a user account in Active Directory. This attribute is used by the Credential Roaming feature of Windows and each AD user can modify their own roamed credentials. AND - A 3rd party application uses the `DSInternals.Common` library to export roamed credentials from Active Directory to a file system. AND - The application has administrative privileges on the local system. The probability of any 3rd-party product using the `DSInternals.Common` library being affected by this vulnerability is extremely low. ### Patches The issue had been fixed in DSInternals 4.8. ### References https://www.mandiant.com/resources/blog/apt29-windows-credential-roaming
