一、漏洞详情
Windows Lightweight Directory Access Protocol (LDAP)是一种基于LDAP协议的轻量级目录访问协议，广泛用于Windows Active Directory (AD)环境中，用来访问和管理目录服务信息。
近日，监测到Windows Lightweight Directory Access Protocol拒绝服务漏洞（CVE-2024-49113）。Windows LDAP服务的wldap32.dll中存在越界读取漏洞，攻击者可以通过未认证的特制DCE/RPC调用（或通过其他方式）诱使目标服务器（作为 LDAP 客户端）向攻击者控制的恶意 LDAP 服务器发起查询请求，当恶意服务器返回特制的、恶意构造的LDAP响应时，可能触发目标服务器中的越界读取漏洞，从而导致拒绝服务（引发LSASS服务崩溃，导致目标系统自动重启，造成服务中断）或信息泄露（导致内存中敏感信息，如凭据、会话数据被泄露）。
建议受影响用户做好资产自查以及预防工作，以免遭受黑客攻击。
