Affected
Brocade Fabric OS
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Brocade Fabric 10.0.1 之前的版本中，SNMP 守护进程在处理请求时存在基于栈的缓冲区溢出漏洞。在处理传入的 SNMPv3 数据包时，一个内部统计信息收集处理程序将用户提供的上下文名称数据复制到固定大小的缓冲区中，但未对字符串长度进行适当验证。在默认配置下，远程未认证攻击者可通过发送特制的 SNMPv3 数据包利用此漏洞，导致内存损坏、守护进程崩溃（拒绝服务）或潜在的任意代码执行。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
A stack-based buffer overflow vulnerability exists in the SNMP daemon request handling of Brocade Fabric versions before 10.0.1. When processing an incoming SNMPv3 packet, an internal statistics gathering handler copies user-supplied context name data into a fixed-size buffer without properly validating the length of the string. A remote, unauthenticated attacker (under default configuration) can exploit this vulnerability by sending a specially crafted SNMPv3 packet, leading to memory corruption, daemon crash (Denial of Service), or potential arbitrary code execution.
