GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

FKIE_CVE-2022-26780

Vulnerability from fkie_nvd - Published: 2022-05-12 17:15 - Updated: 2026-06-17 04:35
Severity
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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_init` function. Controlling the `user_define_timeout` nvram variable can lead to remote code execution.
