Quick assessment
Affected
Brocade Brocade Active Support Connectivity Gateway
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 ASCG 3.5.0 之前的版本中，当处理从远程已被攻陷的终端导入的支持包（support bundle）归档文件时，该应用在提取归档条目之前未能对其中包含的路径遍历序列进行清理。具备发送或拦截待导入归档文件能力的未授权远程攻击者可利用此漏洞，将任意文件写入底层主机上的受限位置，可能导致远程代码执行。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
When Brocade ASCG before 3.5.0 processes support bundle archives ingested from remote compromised endpoints, the application fails to sanitize path traversal sequences contained within archive entries prior to extraction. An unauthenticated remote attacker capable of sending or intercepting ingested archive files can leverage this flaw to write arbitrary files to restricted locations on the underlying host, potentially leading to remote code execution.
