Sharp (and Toshiba Tec rebranded) multifunction printers contain an unauthenticated local file inclusion vulnerability that allows remote attackers to read arbitrary files by manipulating the path parameter in the installed_emanual_down.html endpoint. Attackers can supply directory traversal sequences such as path=/manual/../../../<path> to access files outside the intended manual directory, including /etc/passwd, coredump files containing credentials, and system configuration files. Exploitation evidence was first observed by the Shadowserver Foundation on 2024-07-30.
