漏洞名称： IceWarp Mail Server Open Redirect Vulnerability

漏洞编号：

  • CVE： CVE-2025-40630

漏洞等级： 中危

漏洞描述： IceWarp Mail Server是一款广泛使用的邮件服务器软件，适用于企业级邮件服务部署，支持多种邮件协议和功能，如SMTP、POP3、IMAP等，常用于企业通信系统中。该软件在11.4.0及以下版本中存在一个开放重定向漏洞，攻击者可以通过构造恶意的URL，将用户重定向到任意外部域名。此漏洞的技术根源在于服务器未对重定向URL进行充分的验证和限制，导致攻击者可以利用特定的URL构造方式绕过安全措施。这种漏洞可能导致用户被诱导访问恶意网站，进而遭受钓鱼攻击或凭证窃取等安全威胁。由于攻击者无需认证即可利用此漏洞，且可以自动化执行，因此对用户构成了中等级别的安全风险。
