CVE-2022-1248

7.3 HIGH

📋 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

Products:
  • SAP Information System
Versions: 1.0.0
Operating Systems: Any OS running the web application
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability exists in the default installation. No special configuration is required for exploitation.

📦 What is this software?

⚠️ 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.

🌐 Internet-Facing: HIGH - Unauthenticated remote exploitation makes internet-facing instances extremely vulnerable to automated attacks.
🏢 Internal Only: HIGH - Even internally, any user on the network can exploit this to gain administrative privileges.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

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

all

Use 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

all

Add 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"
