Description

The corresponding PR for this commonlib PR: SpecterOps/SharpHoundCommon#236

Motivation and Context

See commonlib PR.

How Has This Been Tested?

Locally.

Types of changes

• Chore (a change that does not modify the application functionality)
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

Checklist:

• Documentation updates are needed, and have been made accordingly.
• I have added and/or updated tests to cover my changes.
• All new and existing tests passed.
• My changes include a database migration.

Summary by CodeRabbit

• New Features
  • Certificate authority records now show whether disabled-extension information was collected. The status is false when collection does not provide that information.

Walkthrough

ProcessEnterpriseCA collects disabled-extension data and reports whether collection succeeded in the CA output.

Changes

Enterprise CA processing

Layer / File(s)	Summary
Disabled-extension collection and output src/Runtime/ObjectProcessors.cs	ProcessEnterpriseCA collects disabled extensions, records collection status, and adds disabledextensionscollected to the CA properties.

Estimated code review effort: 2 (Simple) | ~5 minutes

Change: Feature

Suggested reviewers: definitelynotagoblin

Merge Risk: Moderate · up to df754

The new disabled-extensions collection depends on a SharpHoundCommon release that the stable package source does not yet provide. A stable release build would fail until the Common dependency is updated to a version with these APIs. Update it before publishing.

Security architecture risk: Low · up to df754

The change follows the existing CA collection controls and does not visibly introduce a new credential source or target-selection path. Remaining uncertainty concerns the companion library’s implementation, compatibility, and failure behavior, which could affect completeness of security inventory.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — At the application boundary, the additional operation is limited to Enterprise CA entries processed with CARegistry enabled and uses the existing CA name, DNS hostname, and HostingComputer arguments. Actual remote access scope and credential use cannot be bounded further without the companion implementation.

Trust Boundaries and Controls

• observed — CA target inputs originate from directory properties. The added call uses the existing CertAbuseProcessor, registry accessor, and SAM accessor rather than introducing a new caller-side credential source or resolver. Whether the new dependency method preserves those authentication and target boundaries remains unresolved.

Resilience and Maintainability Implications

• inferred — If DisabledExtensions propagates an exception or cancellation, the subsequent CASecurity read and EnterpriseCA publication are not reached; the consumer logs processing exceptions and continues without that object. Existing registry reads already share this failure boundary. The new operation adds a possible interruption point, but its unavailable failure contract does not establish an observed inventory-loss defect.

Add the missing object-initializer separator.

DisabledExtensions requires a trailing comma before CASecurity. Without it, the CARegistryData initializer does not compile.

                        DisabledExtensions = await _certAbuseProcessor.DisabledExtensions(dnsHostName, caName, ret.HostingComputer)

                        // The CASecurity exist in the AD object DACL and in registry of the CA server. We prefer to use the values from registry as they are the ground truth.
                        // If changes are made on the CA server, registry and the AD object is updated. If changes are made directly on the AD object, the CA server registry is not updated.
                        CASecurity = await _certAbuseProcessor.ProcessRegistryEnrollmentPermissions(caName,

Proposed fix

-                        DisabledExtensions = await _certAbuseProcessor.DisabledExtensions(dnsHostName, caName, ret.HostingComputer)
+                        DisabledExtensions = await _certAbuseProcessor.DisabledExtensions(dnsHostName, caName, ret.HostingComputer),

Update the stable Common library version.

SharpHoundCommon 4.9.1 lacks both CARegistryData.DisabledExtensions and CertAbuseProcessor.DisabledExtensions. The stable release build cannot compile. Use a stable package version that provides both APIs.
