Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-27751, published on 2026-02-27, is a default credentials vulnerability classified under CWE-1392 in the SODOLA SL902-SWTGW124AS firmware versions through 200.1.20. This flaw stems from hardcoded default credentials in the device's management interface, with no enforcement requiring users to change them upon initial setup. The vulnerability enables remote attackers to authenticate and obtain administrative access, earning a critical CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

Any remote attacker with network access to the management interface can exploit this vulnerability without needing privileges, user interaction, or special conditions. Successful authentication using the default credentials grants full administrative control over the switch, allowing attackers to reconfigure settings, monitor traffic, or disrupt operations, with high impacts on confidentiality, integrity, and availability.

Mitigating Controls (NIST 800-53 r5) AI

CM-6 Configuration Settings good match

Secure configuration settings establish baselines that prohibit default credentials on system components.

IA-5 Authenticator Management good match

Authenticator management requires verification of identity and secure distribution of initial authenticators, directly stopping default credentials from being left in place.

RA-5 Vulnerability Monitoring and Scanning good match

Vulnerability scanning can discover default credentials after deployment but does not stop their introduction.

AC-2 Account Management partial match

Account management processes include assignment and control of initial account credentials, reducing the chance defaults remain active.

PR.PS-01 full match
prevents

Hardened baselines and configuration management explicitly prohibit default credentials on deployed systems.

PR.AA-01 mostly match
prevents

Credential management processes directly require replacing or disabling default passwords and keys.

PR.AA-03 partial match
prevents

Authentication policies can enforce non-default credential strength but do not explicitly address initial deployment defaults.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.9 Configuration management mostly match
prevents

The requirement to replace vendor default authentication information immediately after installation directly counters the use of default credentials that attackers commonly target.
