CVE-2026-3697 Details
Description
A vulnerability was determined in Planet ICG-2510 1.0_20250811. The impacted element is the function sub_40C8E4 of the file /usr/sbin/httpd of the component Language Package Configuration Handler. Executing a manipulation of the argument Language can lead to stack-based buffer overflow. The attack can be launched remotely. The vendor was contacted early about this disclosure but did not respond in any way.
A stack-based buffer overflow vulnerability has been identified in the Planet ICG-2510 product, specifically in the 1.0_20250811 firmware version. The issue arises in the 'sub_40C8E4' function of the '/usr/sbin/httpd' component, which handles language package configurations. The vulnerability can be exploited remotely by manipulating the 'language' configuration value in NVRAM. The function retrieves this value and uses 'sprintf' to format it into a heap-allocated buffer of only 60 bytes. If an attacker sets the 'language' value to a string longer than 48 characters, it will overflow the buffer, potentially leading to memory corruption.
