Detection & IOCsextracted from sources · hover to see the quote
- →CVE-2024-43642 targets Windows SMB and is rated 'Exploitation More Likely' by Microsoft, making SMB traffic anomaly detection a priority — monitor for malformed or unexpected SMB packets that could trigger a denial-of-service condition on exposed Windows hosts. ↗
- →The vulnerability is in the Windows SMB component; ensure SMB ports (445/TCP, 139/TCP) are not exposed to untrusted networks and monitor for unusual SMB connection patterns or crashes in the SMB service (srv2.sys / srvnet.sys). ↗
- →Customer action is required — patch with the relevant KB updates (KB5046617, KB5046696, KB5046616, KB5046698, KB5046633, KB5046618) and verify deployment to reduce exploitation risk. ↗
- ·No public exploit code has been confirmed at time of disclosure; exploitation status may change and should be re-evaluated as new information emerges. ↗

CVE-2024-43639 [CRITICAL] November Patch Tuesday release contains three critical remote code execution vulnerabilities
The Patch Tuesday for November of 2024 includes 89 vulnerabilities, including four that Microsoft marked as “critical.” The remaining vulnerabilities listed are classified as “important.”
Microsoft assessed that exploitation of the four “critical” vulnerabilities is “less likely.”
CVE-2024-43639 is a remote code execution vulnerability in Windows Kerberos that could be exploited by an attacker by creating a specially crafted application to leverage a vulnerable cryptographic protocol. While considered “critical” it was determined that exploitation is “less likely” and not been detected in the wild.
CVE-2024-43625 is a privilege escalation vulnerability in a VMSwitch driver, which is a networking component of Hyper-V. An attacker could exploit this by sending a specific series of network
