CVE-2026-45255— FreeBSD 操作系统命令注入漏洞

Remote code execution via installer Wi-Fi access point scans

When bsdinstall or bsdconfig are prompted to scan for nearby Wi-Fi networks, they build up a list of network names and use bsddialog(1) to prompt the user to select a network. This is implemented using a shell script, and the code which handled network names was not careful to prevent expansion by the shell. As a result, a suitably crafted network name can be used to execute commands via a subshell. The problem can be exploited to execute code as root on the system running bsdinstall or bsdconfig. The attacker would need to create an access point with a specially crafted name and be within range of a Wi-Fi scan. Note that bsdinstall and bsdconfig are vulnerable as soon as the user prompts them to scan for nearby networks; they do not need to actually select the malicious network.

FreeBSD 操作系统命令注入漏洞

FreeBSD是FreeBSD基金会的一套类Unix操作系统。 FreeBSD存在操作系统命令注入漏洞，该漏洞源于扫描Wi-Fi网络时未防止shell扩展网络名称，可能导致特制网络名称通过子shell执行命令，攻击者需创建具有特制名称的接入点并在Wi-Fi扫描范围内，用户提示扫描时即触发漏洞，无需选择恶意网络。
