CWE-287Published: April 27, 2023· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

This 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.

Risk Analysis

GajShield Data Security Firewall firmware uses insecure default credentials, allowing remote attackers to gain superuser access. This poses a critical risk as it grants full control over the firewall.

The vulnerability is remotely exploitable, but there is no known public exploit or CISA KEV entry.

Recommended Action

Update firmware to version 4.28 or higher and ensure all default passwords are changed to strong, unique credentials.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2023-1778 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-287): Authentication bypass vulnerabilities allow attackers to access protected resources without valid credentials.
