Exploitation Probability (EPSS)

Elevated risk
0.82%

56th percentile - higher than 56% of all known CVEs

Summary

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.

Risk Assessment

An attacker can read critical system files, including credentials and configuration files, potentially leading to full compromise of the device and network. Exploitation evidence was first observed on 2024-07-30.

Recommendation

Update the firmware of Sharp and Toshiba Tec printers to a patched version. Until then, restrict network access to the printer web interface and monitor for exploitation attempts.
