发布时间:2018-09-08 07:51
【摘要】:针对网络通讯软件的Fuzzing技术受限于协议格式,尤其是未知协议难以保证测试效果,提出了基于符号表达式的协议分析方法.将数据包关键处理代码翻译为符号表达式,利用符号表达式的丰富含义加快未知协议格式分析,并依此开发了协议格式分析及漏洞挖掘框架PAVD.通过对亿邮客户端的漏洞测试,验证了PAVD能有效提升协议分析效率,为网络通讯软件Fuzzing测试提供良好的支持.
[Abstract]:In view of the fact that the Fuzzing technology of network communication software is limited by the protocol format, especially the unknown protocol is difficult to guarantee the test effect, a protocol analysis method based on symbolic expression is proposed. The key processing code of data packet is translated into symbolic expression, and the rich meaning of symbol expression is used to accelerate the analysis of unknown protocol format. Based on this, a protocol format analysis and vulnerability mining framework PAVD. is developed. By testing the vulnerability of Yipu client, it is proved that PAVD can effectively improve the efficiency of protocol analysis and provide a good support for Fuzzing test of network communication software.
