How the Vulnerability Works
CVE-2025-49002 affects DataEase versions before 2.10.10, where an incomplete patch for CVE-2025-32966 fails to properly restrict SQL commands due to case sensitivity issues. The patch attempted to block `INIT` and `RUNSCRIPT` commands but did not account for mixed-case variants (e.g., InIt, RuNsCrIpT). Attackers can bypass filters by altering letter cases, leading to arbitrary SQL execution. This allows database manipulation, privilege escalation, or remote code execution. The flaw stems from improper input validation in the query parser, enabling injection via crafted requests.
DailyCVE Form
Platform: DataEase
Version: < 2.10.10
Vulnerability: SQLi Bypass
Severity: Critical
Date: 06/05/2025
Prediction: Patch expected by 06/20/2025
What Undercode Say:
Exploitation
1. Craft Malicious Query:
SELECT FROM users WHERE id = 1; InIt('malicious_script'); --
2. Case Variation:
POST /query HTTP/1.1
Host: target.com
Body: {"cmd": "rUnScRiPt('payload')"}
3. Tool: Use `sqlmap` with tamper scripts for case evasion:
sqlmap -u http://target.com/query --tamper=randomcase.py
Protection
1. Patch: Upgrade to v2.10.10.
2. WAF Rules:
location /query {
if ($args ~ "(?i)(init|runscript)") { return 403; }
}
3. Input Validation:
def sanitize_sql(cmd): return re.sub(r'(?i)(init|runscript)', '', cmd)
Detection
1. Log Monitoring:
grep -Ei "init|runscript" /var/log/dataease/access.log
2. IDS Signature:
alert http any any -> any any (msg:"DataEase SQLi Attempt"; content:"init"; nocase; sid:10049002;)
Mitigation
1. Disable Dynamic Queries:
// DataEase config allowDynamicSQL = false;
2. Error Masking:
<error-page> <exception-type>java.sql.SQLException</exception-type> <location>/generic-error.html</location> </error-page>
Analytics
- Attack Surface: High (public-facing BI tools).
- Exploitability: Low skill required due to tooling.
- Impact: Full database compromise.
Post-Patch Verification
curl -X POST http://patched-host/query -d '{"cmd":"INIT(test)"}' | grep -q "Blocked" && echo "Secure"
