🧨 Overview
A critical zero-day vulnerability tracked as CVE‑2025‑31324 in SAP Visual Composer has been actively exploited in the wild, according to SAP, global threat researchers, and the U.S. CISA.This flaw holds a CVSS score of 10.0 — the highest possible — and allows unauthenticated remote attackers to upload arbitrary files on vulnerable systems. The result? Complete system compromise.
🚨 CISA has added this to the KEV (Known Exploited Vulnerabilities) Catalog. Urgent action is required.
📌 Key Details
- CVE: CVE‑2025‑31324
- Severity: 10.0 (Critical)
- Affected Software: SAP Visual Composer
- Access Vector: Remote (Unauthenticated)
- Exploit Status: Actively Exploited
- Impact: Remote Code Execution (RCE), Data Exfiltration, Backdoor Deployment
- Attack Complexity: Low
🧠 Technical Breakdown
The vulnerability lies in the file upload handler of SAP Visual Composer. It fails to properly validate file types and paths, enabling attackers to:
- Upload malicious scripts (e.g. JSP, WAR files)
- Achieve persistent backdoor access
- Escalate privileges via chained flaws
- Trigger RCE inside core SAP infrastructure
🎯 Why It Matters
SAP powers financials, manufacturing, ERP, and HR systems globally. This exploit targets Visual Composer — a platform used to build SAP apps quickly, often exposed externally via web.A breach here may expose:
- Sensitive financial and HR data
- Operational workflows
- SAP administrator credentials
- Gateway access to other SAP services
🛡️ CyberDudeBivash Recommendations
✅ Mitigation Checklist
- Apply Patches:
If a fix is available via SAP Security Notes, apply it immediately. - Restrict Upload Paths:
Prevent upload features from accepting executable files. - WAF Rules & Reverse Proxies:
Implement rules to block suspicious upload requests. - Monitor Logs for Suspicious Activity:
Focus on unusual .jsp, .war, or .exe access patterns. - Isolate SAP Internet-Facing Interfaces:
Segment exposed systems and remove public access where possible. - Backup and DR Readiness:
Assume breach — validate disaster recovery and backup integrity.
