[原文]Multiple buffer overflows in libnasl in Nessus before 2.0.6 allow local users with plugin upload privileges to cause a denial of service (core dump) and possibly execute arbitrary code via (1) a long proto argument to the scanner_add_port function, (2) a long user argument to the ftp_log_in function, (3) a long pass argument to the ftp_log_in function.


[CNNVD]Nessus LibNASL任意代码执行漏洞(CNNVD-200306-077)

        Nessus 2.0.6版本libnasl存在多个缓冲区溢出漏洞。具有插件上传特权的本地用户借助(1)scanner_add_port函数的超长proto参数,(2)ftp_log_in函数的超长user参数,(3)ftp_log_in函数的超长pass参数导致服务拒绝(内存转储)并可能执行任意代码。

Nessus libnasl ftp_log_in Function Local Overflow
Local Access Required Input Manipulation
Loss of Integrity Upgrade
Vendor Verified

- 漏洞描述

Nessus contains a flaw that allows a local user to create a denial of service to the scanner. The condition is due to a flaw in the Nessus Attack Scripting Language (NASL) engine when the "plugins_upload" option is enabled. A local attacker can provide a long "user" or "pass" argument to the ftp_log_in() function and cause the NASL to crash.
