Detection & IOCs extracted from sources · hover to see the quote

• → The vulnerability is exploitable remotely over HTTP without authentication, targeting Oracle E-Business Suite Common Applications Calendar component. Network-level detection should monitor for anomalous unauthenticated HTTP requests to Oracle E-Business Suite Calendar endpoints. ↗
• → The attack vector requires human interaction (e.g., a victim clicking a crafted link), suggesting a reflected/stored XSS or CSRF-style delivery mechanism. Monitor for suspicious cross-origin requests or unexpected redirects involving Oracle EBS Calendar URLs. ↗
• → The scope is Changed (S:C in CVSS vector), meaning a successful exploit can impact components beyond Oracle Common Applications Calendar itself. Correlate alerts across Oracle EBS components when Calendar anomalies are detected. ↗

• · Affected versions are Oracle E-Business Suite 12.1.1 through 12.1.3 and 12.2.3 through 12.2.10. Ensure patching scope covers both the 12.1.x and 12.2.x release trains. ↗
