Default Credential Vulnerability in GajShield Data Security Firewall

Original Issue Date:April 26, 2023

Severity Rating: CRITICAL

Software Affected

  • GajShield Data Security Firewall- all firmware versions prior to v4.28 except v4.21

Overview

A vulnerability has been identified in GajShield Data Security Firewall (all firmware versions prior to v4.28 except v4.21) which could allow remote attacker to execute arbitrary commands with administrative privileges on the targeted systems.

Description

The vulnerability exists in GajShield Data Security Firewall firmware versions prior to v4.28 (except v4.21) due to insecure default credentials which allows remote attacker to login as superuser by using default username/password via web-based management interface and/or exposed SSH port thereby enabling remote attackers to execute arbitrary commands with administrative/superuser privileges on the targeted systems.

The vulnerability has been addressed by forcing the user to change their default password to a new non-default password.

Note: This vulnerability (CVE-2023-1778) is being exploited in the wild. Users are advised to update the firmware urgently.

Credit: This vulnerability is identified by Prashant Pandey from Indian Computer Emergency Response Team (CERT-In).
