[原文]Unknown vulnerability in ecartis before 1.0.0 does not properly validate user input, which allows attackers to obtain mailing list passwords.


[CNNVD]ECartis LIScript任意变量查看漏洞(CNNVD-200405-022)

        
        Ecartis是一款邮件列表管理器。
        Ecartis没有正确处理用户提供的输入,远程攻击者可以利用这个漏洞未授权获得敏感信息。
        Ecartis包含的liscript支持部分变量和函数,部分地方对用户输入完全可信,允许调用部分函数或查看变量,用户提交如下的请求:
        subscribe secret-list
        subscribe <$post-password>
        第一条命令会失败,但是Ecartis会选择secre-list作为活动列表,第二条命令也不成功,但是返回的邮件会包含post-password的实际密码信息。
