CVE-2022-26782: Inhandnetworks ir302 firmware improper input validation vulnerability

Inhandnetworks · Ir302 Firmware

Multiple improper input validation vulnerabilities exists in the libnvram.so nvram_import functionality of InHand Networks InRouter302 V3.5.4. A specially-crafted file can lead to remote code execution. An attacker can send a sequence of requests to trigger this vulnerability.An improper input validation vulnerability exists in the `httpd`'s `user_define_set_item` function. Controlling the `user_define_timeout` nvram variable can lead to remote code execution.
