Title

Cisco ASA Software的Identity Firewall功能存在缓冲区溢出漏洞

Description

Cisco Adaptive Security Appliance（ASA，自适应安全设备）是美国思科（Cisco）公司的一套防火墙设备。该设备还包括IPS（入侵防御系统）、SSL VPN、IPSec VPN、反垃圾邮件等功能。 Cisco ASA Software的Identity Firewall功能存在缓冲区溢出漏洞。由于Cisco ASA防火墙对NetBIOS协议数据解析时产生溢出错误，攻击者利用漏洞可对内存数据进行覆盖，从而执行任意代码，获取系统控制权，或造成受影响系统重载。

CVE-2016-6432 (GCVE-0-2016-6432)

Vulnerability from cvelistv5 – Published: 2016-10-27 21:00 – Updated: 2024-08-06 01:29

Summary

A vulnerability in the Identity Firewall feature of Cisco ASA Software before 9.6(2.1) could allow an unauthenticated, remote attacker to cause a reload of the affected system or to remotely execute code. The vulnerability is due to a buffer overflow in the affected code area. An attacker could exploit this vulnerability by sending a crafted NetBIOS packet in response to a NetBIOS probe sent by the ASA software. An exploit could allow the attacker to execute arbitrary code and obtain full control of the system or cause a reload of the affected system. Note: Only traffic directed to the affected system can be used to exploit this vulnerability. This vulnerability affects systems configured in routed and transparent firewall mode and in single or multiple context mode. This vulnerability can be triggered by IPv4 traffic.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
