低危 putty putty 对数据真实性的验证不充分
CVE编号
CVE-2021-36367利用情况
暂无补丁情况
官方补丁披露时间
2021-07-10漏洞描述
PuTTY through 0.75 proceeds with establishing an SSH session even if it has never sent a substantive authentication response. This makes it easier for an attacker-controlled SSH server to present a later spoofed authentication prompt (that the attacker can use to capture credential data, and use that data for purposes that are undesired by the client user).解决建议
建议您更新当前系统或软件至最新版，完成漏洞的修复。
