Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-27757, published on 2026-02-27, is an authentication vulnerability (CWE-620) in the SODOLA SL902-SWTGW124AS firmware versions through 200.1.20. The flaw allows authenticated users to change account passwords without verifying the current password, enabling unauthorized credential modifications. It has a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N), indicating high integrity impact potential over the network.
Attackers require low privileges (PR:L) to exploit this vulnerability, gaining initial access to an authenticated session on the management interface. Once authenticated, exploitation is straightforward with low complexity and no user interaction needed. Successful attacks allow the adversary to alter passwords, securing persistent access to the device and potentially enabling further compromise of the network switch.
Advisories and vendor resources provide further details on the issue.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Re-authentication explicitly requires users to prove identity before performing sensitive actions such as password changes.
Authenticator management requires identity verification during password distribution and changes, directly stopping unverified password updates.

Requires secure management of authentication information, directly addressing the need to verify the original password before allowing a change.
Mandates secure authentication mechanisms, which include verifying existing credentials before permitting password changes.
Identity management processes can incorporate verification steps, but the control itself does not explicitly require password-change verification.
Information access restriction can be strengthened by password verification, yet the control focuses on access rights rather than change procedures.
