[CNNVD]SMTP Proxy远程格式串处理漏洞(CNNVD-200412-210)

        
        SMTP Proxy是SMTP代理服务器程序。
        SMTP Proxy在处理SMTP头字段时存在格式串问题,远程攻击者可以利用这个漏洞可能以进程权限在系统上执行任意指令。
        攻击者发送客户端主机名或message-id包含格式串的消息给SMTP Proxy服务器,在被snprintf()格式化然后发送带syslog()并被解析为格式串时会触发内存破坏问题,精心构建提交数据可能以进程权限在系统上执行任意指令。

smtp.proxy smtp.c Format String Arbitrary Command Execution
Remote / Network Access, Local / Remote, Context Dependent Input Manipulation
Loss of Confidentiality, Loss of Integrity, Loss of Availability

- 漏洞描述

smtp.proxy contains a flaw that may allow a malicious user to perform format string attack. The issue is due to a format string error in "smtp.c" function. By sending a specially crafted message containing a format string in either the client hostname or the message-id, a remote attacker can crash the proxy server and execute arbitrary code on the compromised system, resulting in a loss of confidentiality, integrity, and/or availability.
