  Oracle has disclosed a critical vulnerability (CVE-2025-61882) affecting E-Business Suite versions 12.2.3 through 12.2.14. This pre-authentication remote code execution (RCE) flaw enables unauthenticated attackers to exploit multiple chained weaknesses — including SSRF, CRLF injection, authentication bypass, and unsafe XSLT processing — to gain full control of affected systems. Risk Assessment: Severity: Critical (CVSS 9.8) Exposure: Internet-facing Oracle EBS instances are at immediate risk Threat Activity: Active exploitation confirmed by threat intelligence sources, including Cl0p ransomware group Business Impact: Potential compromise of financial systems, data exfiltration, and operational disruption Recommended Actions: Immediate Patch Deployment: Apply Oracle’s July 2025 Critical Patch Update to all affected EBS environments. Network Segmentation: Restrict public access to Oracle EBS systems. Ensure they are isolated from internet-facing zones. Threat Monito...

Microsoft Defender for Endpoint (DFE) and Mitigation for It

-
Image
  The recent vulnerability affecting Microsoft Defender for Endpoint (DFE) involves critical flaws in how the agent communicates with its cloud backend, potentially allowing attackers to bypass authentication and manipulate incident response processes. Key Vulnerabilities in Defender for Endpoint (DFE) Authentication Bypass : Attackers can impersonate the Defender agent using only the machine ID and tenant ID, which are accessible to low-privileged users via registry reads. This allows them to spoof commands and responses. Command Interception : By querying endpoints like /edr/commands/cnc , attackers can intercept or fake responses (e.g., falsely reporting a device as isolated), undermining actual security status. Certificate Pinning Circumvention : Researchers bypassed HTTPS protections by patching memory functions (e.g., CRYPT32!CertVerifyCertificateChainPolicy ) to inspect traffic in plaintext using tools like Burp Suite and WinDbg. Azure Blob Upload Exploits : Attackers c...
