How to Write Effective Pentest Reports: Precision, Clarity, and Actionability

Listen to this Post

Great pentest reports are not about volume but about delivering precise, clear, and actionable insights that enable organizations to remediate vulnerabilities quickly. Below is a breakdown of what makes a pentest report effective, along with practical commands and steps to apply these principles.

Key Elements of a Strong Pentest Report

  1. Precision – Clearly identify the vulnerability, affected systems, and exploitation steps.
  2. Clarity – Avoid jargon; explain findings in a way that both technical and non-technical stakeholders understand.
  3. Actionability – Provide remediation steps, references, and proof of concept (PoC) where applicable.

Example: Privilege Escalation via Insecure Delegated Permissions

Bad Report Example:

“Privilege escalation to Domain Admin was achieved by abusing insecure permissions.”

Good Report Example:

“Privilege escalation to Domain Admin as a Domain User (jdoe) was achieved by abusing insecure delegated permissions. Domain Users was granted FullControl of the Domain Admins group, allowing jdoe to add themselves to the group.”

Remediation Steps:

  • Remove `FullControl` permissions from the `Domain Admins` group.
  • Ensure `Domain Users` is not listed in the ACL of Domain Admins.
  • Use `dsacls` or Active Directory Users and Computers (ADUC) to verify permissions.

You Should Know: Practical Commands & Steps

1. Checking Active Directory Permissions

 List ACLs of the Domain Admins group 
dsacls "CN=Domain Admins,CN=Users,DC=example,DC=com" 

2. Exploiting Insecure Delegation (PoC)

 Using crackmapexec to check for delegation misconfigurations 
crackmapexec ldap <DC_IP> -u <user> -p <password> --delegation 

3. Remediation via PowerShell

 Remove FullControl for Domain Users 
$ADGroup = Get-ADGroup "Domain Admins" 
$ADGroup | Set-ADObject -Remove @{ntSecurityDescriptor=(Get-ACL "AD:\$($ADGroup.DistinguishedName)").Access} 

4. Verifying Fixes

 Using BloodHound to confirm no excessive permissions remain 
bloodhound-python -d example.com -u user -p 'password' -c All 

What Undercode Say

A pentest report is only as good as its ability to drive security improvements. Avoid vague statements—instead, provide:
– Step-by-step exploitation details (with annotated screenshots).
– Exact commands used (for reproducibility).
– Clear remediation guidance (with official references).
– Business impact analysis (why this matters to executives).

Expected Output:

A well-structured pentest report that enables quick remediation, reduces organizational risk, and strengthens security posture.
