Introduction
SCCM (System Center Configuration Manager) servers often store sensitive data in the hidden `SCCMContentLib$` share, accessible by any authenticated user in an Active Directory environment. Daniel E.’s newly released tool, SCCM SLAP (Secret Locator and Package Analyzer), automates the extraction and analysis of these files, exposing potential security flaws. This article dives into how SLAP works, key commands, and best practices for defenders.
Learning Objectives
- Understand how SCCM SLAP automates credential harvesting from SCCMContentLib$.
- Learn defensive techniques to secure SCCM shares against unauthorized access.
- Explore advanced SCCM penetration testing methodologies.
You Should Know
1. Installing and Running SCCM SLAP
Command:
git clone https://github.com/redi-git/SLAP.git cd SLAP pip install -r requirements.txt python3 slap.py --help
Step-by-Step Guide:
1. Clone the repository to your local machine.
2. Install dependencies using `pip`.
- Run SLAP with `–help` to see available options (e.g.,
--scan,--download). - Use `-t` to specify a target SCCM server and `-u/-p` for credentials if needed.
2. Scanning for Secrets with Regex
Command:
python3 slap.py -t sccm.example.com -u DOMAIN\user -p Password123 --scan --regex "(password|key|secret)"
What This Does:
- Searches `SCCMContentLib$` for files containing keywords like password, key, or secret.
- Outputs findings in a structured report for further analysis.
3. Downloading Full Packages for Offline Analysis
Command:
python3 slap.py -t sccm.example.com --download --output ~/sccm_dump
Step-by-Step Guide:
- Executes a full download of SCCM packages to a local directory.
- Allows deeper forensic analysis of scripts, executables, and configuration files.
4. Generating a CSV Inventory Report
Command:
python3 slap.py -t sccm.example.com --inventory --csv report.csv
What This Does:
- Creates an Excel/CSV-friendly inventory of all files in
SCCMContentLib$. - Useful for compliance audits and security assessments.
5. Bypassing Secured Datalibs
Command:
python3 slap.py -t sccm.example.com --bypass --scan
How It Works:
- Some SCCM deployments restrict access to certain files. SLAP bypasses these restrictions by leveraging known file structure weaknesses.
6. Defending Against SCCM SLAP Attacks
Mitigation Steps:
1. Restrict Share Permissions:
icacls \sccm-server\SCCMContentLib$ /deny "Authenticated Users:(R)"
2. Enable SMB Encryption:
Set-SmbServerConfiguration -EncryptData $true
3. Monitor Access Logs:
Get-WinEvent -LogName "Security" -FilterXPath "[EventData[Data[@Name='ObjectName']='\sccm-server\SCCMContentLib$']"
7. Automating SCCM Security Audits
PowerShell Script to Check Vulnerable Shares:
$shares = Get-SmbShare | Where-Object { $_.Name -like "SCCM" }
foreach ($share in $shares) {
$perms = Get-SmbShareAccess -Name $share.Name
if ($perms.AccountName -contains "Authenticated Users") {
Write-Warning "Vulnerable Share Found: $($share.Name)"
}
}
What Undercode Say
- Key Takeaway 1: SCCM SLAP exposes a critical misconfiguration in SCCM deployments—default read access for authenticated users.
- Key Takeaway 2: Organizations must enforce strict share permissions and SMB encryption to prevent credential leaks.
Analysis:
SCCM servers are often overlooked in security assessments, yet they store deployment scripts, credentials, and sensitive configurations. Tools like SLAP highlight the need for proactive hardening. Expect increased exploitation as attackers automate SCCM reconnaissance.
Prediction
As SCCM SLAP gains traction, we’ll see a surge in SCCM-based lateral movement attacks, pushing enterprises to adopt stricter access controls and real-time monitoring. Future versions of SLAP may incorporate AI-driven secret detection, making it even more dangerous in the wrong hands.
Final Word: Defenders must act now—audit SCCM permissions, restrict share access, and monitor for anomalous file reads. Offensive tools like SLAP are a wake-up call for better configuration management.
