Threat & Defense at a Glance

What attackers do: exploitation maps to Default Accounts (T1078.001) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

IA-5 Authenticator Management good match

prevent

IA-5 directly and comprehensively addresses hard-coded credentials by requiring management of authenticators including changing defaults prior to use and protecting them from unauthorized disclosure.

SI-2 Flaw Remediation good match

prevent

SI-2 mandates identification, assessment, and timely remediation of flaws such as CVE-2026-23647 through software updates and configuration changes per vendor guidance.

AC-2 Account Management partial match

prevent

AC-2 partially mitigates by requiring account management processes to authorize, monitor, and deactivate unnecessary privileged accounts with embedded passwords.

MITRE ATT&CK Enterprise TechniquesAI

T1078.001 Default Accounts Stealth

Adversaries may obtain and abuse credentials of a default account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.

attack.mitre.org →

T1133 External Remote Services Persistence

Adversaries may leverage external-facing remote services to initially access and/or persist within a network.

Why these techniques?

Hard-coded credentials in local accounts, including administrative ones, enable use of default accounts (T1078.001) for unauthorized remote access via exposed external remote services such as SSH (T1133).

NVD Description

Glory RBG-100 recycler systems using the ISPK-08 software component contain hard-coded operating system credentials that allow remote authentication to the underlying Linux system. Multiple local user accounts, including accounts with administrative privileges, were found to have fixed, embedded passwords. An…

attacker with network access to exposed services such as SSH may authenticate using these credentials and gain unauthorized access to the system. Successful exploitation allows remote access with elevated privileges and may result in full system compromise.

Deeper analysisAI

CVE-2026-23647 is a critical vulnerability in Glory RBG-100 recycler systems that use the ISPK-08 software component. It stems from hard-coded operating system credentials on the underlying Linux system, where multiple local user accounts—including those with administrative privileges—have fixed, embedded passwords. Classified under CWE-798 (Use of Hard-coded Credentials), this flaw allows remote authentication without requiring legitimate user interaction.

Any attacker with network access to exposed services, such as SSH, can exploit the vulnerability by using the known credentials to authenticate. No special privileges, user interaction, or complex conditions are needed, enabling straightforward remote access with elevated privileges and potential full system compromise. The issue carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting its high impact on confidentiality, integrity, and availability.
