CVE-2023-44794
📋 TL;DR
CVE-2023-44794 is a critical privilege escalation vulnerability in Dromara SaToken authentication framework. Remote attackers can send crafted payloads to URLs to gain elevated privileges. All systems running vulnerable SaToken versions are affected.
💻 Affected Systems
- Dromara SaToken
📦 What is this software?
Sa Token by Dromara
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with administrative access, data theft, and lateral movement across the network.
Likely Case
Unauthorized access to sensitive data, privilege escalation to administrative functions, and potential data manipulation.
If Mitigated
Limited impact with proper input validation, network segmentation, and least privilege principles in place.
🎯 Exploit Status
Exploitation requires sending crafted payloads to vulnerable endpoints, which is straightforward given the public PoC.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.37.0 or later
Vendor Advisory: https://github.com/dromara/Sa-Token/issues/515
Restart Required: Yes
Instructions:
1. Update SaToken dependency to version 1.37.0 or later. 2. Rebuild and redeploy the application. 3. Restart the application server.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for URL parameters to block malicious payloads.
Web Application Firewall (WAF)
allDeploy WAF rules to detect and block crafted payloads targeting SaToken endpoints.
🧯 If You Can't Patch
- Isolate affected systems from internet and restrict internal network access.
- Implement strict network segmentation and monitor for unusual authentication attempts.
🔍 How to Verify
Check if Vulnerable:
Check the SaToken version in your project's dependency file (e.g., pom.xml for Maven, build.gradle for Gradle).Check Version:
grep -i 'sa-token' pom.xml || grep -i 'sa-token' build.gradleVerify Fix Applied:
Verify the updated SaToken version is 1.37.0 or later and test authentication flows.📡 Detection & Monitoring
Log Indicators:
- Unusual authentication success logs from unexpected IPs
- Multiple failed login attempts followed by successful privileged access
Network Indicators:
- HTTP requests with crafted payloads to authentication endpoints
- Unusual traffic patterns to SaToken-related URLs
SIEM Query:
