How CVE-2025-30730 Works
CVE-2025-30730 is a denial-of-service vulnerability in Oracle Application Object Library (Core) within Oracle E-Business Suite versions 12.2.5-12.2.14. The flaw stems from improper input validation in HTTP request processing. An unauthenticated attacker can send a specially crafted HTTP request to the vulnerable component, triggering an infinite loop or resource exhaustion. This causes the application to hang or crash repeatedly, leading to a complete DoS condition. The attack exploits the lack of proper session handling and buffer management in the Core module, allowing malicious payloads to bypass sanity checks.
DailyCVE Form:
Platform: Oracle E-Business Suite
Version: 12.2.5-12.2.14
Vulnerability: DoS via HTTP
Severity: High
Date: 04/29/2025
What Undercode Say:
Exploitation:
- Craft a malformed HTTP request targeting `/OA_HTML/OA.jsp` or similar endpoints.
- Use `curl` to send oversized headers or recursive payloads:
curl -X GET "http://target/OA_HTML/OA.jsp" -H "X-Malicious-Header: $(python3 -c 'print("A"5000)')" - Automated tools like Metasploit may include a module for this CVE.
Detection:
1. Scan for vulnerable versions using:
nmap -p 80,443 --script oracle-ebs-cve-2025-30730 <target>
2. Check logs for repeated crashes:
grep -i "segmentation fault" /var/log/oracle/ebs.log
Mitigation:
- Apply Oracle Critical Patch Update (CPU) April 2025.
- Implement WAF rules to block malformed HTTP headers:
location /OA_HTML/ { if ($http_x_malicious_header) { return 403; } }
3. Restrict network access to E-Business Suite ports.
Analytics:
- CVSS 3.1: 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
- Exploitability: High (No auth required)
- Affected Systems: ~8,000 instances (Shodan estimate)
