Technical Details for CVE-2024-49112

Vulnerability Analysis

This vulnerability stems from improper handling of requests in Microsoft Windows LDAP which allows remote code execution via specially crafted packets. The flaw could be exploited by unauthenticated attackers to run arbitrary code on the affected system.

Root Cause

The root cause is an integer overflow (CWE-190) in the LDAP component that miscalculates buffer sizes, leading to improper memory management.

Attack Vector

This vulnerability can be exploited over the network by sending specially crafted LDAP requests that trigger the overflow condition.

powershell

# Example exploitation code (sanitized)
$ldapRequest = "<malicious_LDAP_request>"
Send-LdapRequest -Server "target_server" -Request $ldapRequest

Detection Methods for CVE-2024-49112

Indicators of Compromise

Unexpected high network traffic to LDAP ports
Presence of anomalous processes executing under directory services context
Unusual LDAP request patterns

Detection Strategies

Implement network monitoring to capture and analyze LDAP traffic for malicious request patterns that match known signatures associated with this vulnerability.

Monitoring Recommendations

Utilize SentinelOne to monitor for suspicious process behaviors linked to directory services and detect any abnormal executions originating from LDAP service.

How to Mitigate CVE-2024-49112

Immediate Actions Required

Apply the latest patches from Microsoft immediately.
Restrict LDAP traffic to only trusted domain controllers.
Implement network segmentation to limit exposure.

Patch Information

Microsoft has released patches for all affected versions. Ensure your systems are updated via the Microsoft Security Update Guide.

Workarounds

Consider disabling the LDAP service temporarily if it is not crucial or using a firewall to block all inbound LDAP traffic except from trusted sources.

bash

# Configuration example
iptables -A INPUT -p tcp --dport 389 -s trusted_host -j ACCEPT
iptables -A INPUT -p tcp --dport 389 -j DROP
