CVE-2026-62184 Details
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.
A log parsing vulnerability has been identified in the OpenWrt LuCI application 'banIP', specifically in versions through 0.11.1. The issue arises from an awk-based parser that extracts the first IPv4 address from log lines without considering the field position. This flaw enables attackers to inject arbitrary IP addresses via fields they control, such as usernames. An unauthenticated remote attacker can exploit this by injecting an IP address into the login username field, leading to the banIP system blocking the wrong target while the actual attacker remains unblocked.
The vulnerability has been patched in banIP version 1.8.10-1. Users should update to this version.
