CVE-2024-28041

Adjacent-network command execution via crafted web request

Published Mar 25, 2024 · Updated Mar 28, 2025

Command injection in web-interface handling in KDDI HGW-BL1500HM 002.001.013 and earlier allows remote attackers to execute arbitrary commands. Request handling for a specific web-interface URL fails to neutralize special characters before placing the supplied string in a command context. The attacker must have adjacent-network reachability but needs neither authentication nor user interaction; arbitrary commands can change gateway settings and operation.
