CVE-2022-1248
📋 TL;DR
CVE-2022-1248 is a critical authentication bypass vulnerability in SAP Information System 1.0 that allows unauthenticated attackers to create new administrative accounts via a simple POST request to /SAP_Information_System/controllers/add_admin.php. This affects all organizations running the vulnerable SAP Information System version, enabling complete compromise of the application.
💻 Affected Systems
- SAP Information System
📦 What is this software?
Sap Information System by Sap Information System Project
⚠️ Risk & Real-World Impact
Worst Case
Complete takeover of the SAP Information System application, allowing attackers to access, modify, or delete sensitive business data, install backdoors, and pivot to other systems.
Likely Case
Attackers create administrative accounts to gain persistent access, exfiltrate sensitive information, and potentially disrupt business operations.
If Mitigated
With proper network segmentation and authentication controls, impact is limited to the isolated application instance.
🎯 Exploit Status
Exploit details are publicly available on Packet Storm Security. The attack requires only a simple HTTP POST request with no authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official SAP advisory found
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Block access to vulnerable endpoint
allUse web application firewall or server configuration to block all access to /SAP_Information_System/controllers/add_admin.php
# Apache: RewriteRule ^/SAP_Information_System/controllers/add_admin\.php$ - [F,L]
# Nginx: location ~ /SAP_Information_System/controllers/add_admin\.php { deny all; }
Implement authentication middleware
allAdd authentication checks before processing any requests to the vulnerable endpoint
🧯 If You Can't Patch
- Remove the SAP Information System from internet-facing networks immediately
- Implement strict network segmentation and limit access to only authorized users
🔍 How to Verify
Check if Vulnerable:
Attempt to send a POST request to /SAP_Information_System/controllers/add_admin.php with admin creation parameters. If it succeeds without authentication, the system is vulnerable.
Check Version:
Check application version in web interface or configuration files
Verify Fix Applied:
After implementing workarounds, attempt the same POST request. It should fail with authentication error or be blocked entirely.
📡 Detection & Monitoring
Log Indicators:
- POST requests to /SAP_Information_System/controllers/add_admin.php from unauthenticated users
- Successful admin account creation logs from unknown IPs
Network Indicators:
- HTTP POST traffic to the vulnerable endpoint without preceding authentication requests
SIEM Query:
source="web_server" AND (uri="/SAP_Information_System/controllers/add_admin.php" OR uri LIKE "%/add_admin.php") AND http_method="POST"
