CVE-2026-81946 Details
Description
PLANET IGS-5225-8P2T4S industrial managed switch V1 and V2 firmware versions before 1.2412b260707 and 2.2412b260519 use MD5-based password hashing, a cryptographic algorithm with known weaknesses. An attacker who obtains the device configuration file can recover the privileged-mode access password.
A vulnerability exists in the PLANET IGS-5225-8P2T4S industrial managed switch, affecting both V1 and V2 firmware releases prior to 1.2412b260707 and 2.2412b260519. The issue arises from the use of MD5 for password hashing, a method known to be cryptographically weak. This flaw allows an attacker who accesses the device's configuration file to retrieve the privileged-mode access password.
Users can upgrade to PLANET IGS-5225-8P2T4S V1 firmware version 1.2412b260707 or V2 firmware version 2.2412b260519. The updated firmware is available for download from the PLANET official website.
