Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

OpenWRT luci是OpenWRT社区开源的一款路由器配置界面。 OpenWRT luci 0.11.1及之前版本存在输出处理不当漏洞，该漏洞源于luci-app-banip的awk解析器从日志行中提取第一个IPv4地址，无论字段位置如何，允许攻击者通过攻击者控制的字段（如用户名）注入任意IP地址，可能导致未经身份验证的远程攻击者在登录用户名字段注入IP地址，导致banIP拦截错误目标。

Vulnerability Title
luci-app-banip Log Monitor IP Extraction Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
luci-app-banip contains a log parsing vulnerability where the awk-based parser extracts the first IPv4 address from log lines regardless of field position, allowing attackers to inject arbitrary IPs via attacker-controlled fields like usernames. An unauthenticated remote attacker can inject an IP address into the login username field, causing banIP to block the wrong target while the real attacker remains unblocked.
