CWE-603

Due to a reliance on client-side authentication, the WiFi Mouse (Mouse Server) from Necta LLC's authentication mechanism is trivially bypassed, which can result in remote code execution.

A vulnerability has been identified in Cerberus DMS (All versions), Desigo CC (All versions), Desigo CC Compact (All versions), SIMATIC WinCC OA V3.16 (All versions in default configuration), SIMATIC WinCC OA V3.17 (All versions in non-default configuration), SIMATIC WinCC OA V3.18 (All versions in non-default configuration). Affected applications use client-side only authentication, when neither server-side authentication (SSA) nor Kerberos authentication is enabled. In this configuration, attackers could impersonate other users or exploit the client-server protocol without being authenticated.

A Use of Client-Side Authentication issue was discovered in Advantech B+B SmartWorx MESR901 firmware versions 1.5.2 and prior. The web interface uses JavaScript to check client authentication and redirect unauthorized users. Attackers may intercept requests and bypass authentication to access restricted web pages.

Produkty IAQS oraz I6 firmy JNC zawierają podatność typu Client-Side Enforcement of Server-Side Security (CWE-603), która umożliwia nieuwierzytelnionemu atakującemu zdalne przejęcie uprawnień administratora. Krytyczna waga podatności (CVSS 9.3) wynika z braku jakichkolwiek wymagań uwierzytelnienia oraz możliwości pełnej kompromitacji systemu.

Podatność w systemie zarządzania baterią Nuvation BMS umożliwia nieuwierzytelnionemu atakującemu ominięcie mechanizmów uwierzytelnienia. Ze względu na krytyczny wynik CVSS 9.3 i brak wymagań wstępnych (sieciowy dostęp, brak interakcji użytkownika), podatność stanowi poważne zagrożenie dla infrastruktury przemysłowej.

Oprogramowanie New Site Server firmy CyberTutor zawiera podatność CWE-603 polegającą na stosowaniu uwierzytelnienia wyłącznie po stronie klienta. Nieuwierzytelniony, zdalny atakujący może zmodyfikować kod frontendu i uzyskać uprawnienia administratora witryny.

Podatność w nadajnikach FM TELSAT Markoni umożliwia atakującemu ominięcie mechanizmu uwierzytelniania i uzyskanie uprawnień administratora bez posiadania żadnych danych logowania. Ze względu na sieciowy charakter ataku i brak wymaganych interakcji użytkownika, zagrożenie jest krytyczne.

System CGM CLININET umożliwia atakującemu uwierzytelnienie się bez fizycznej karty chipowej ani klucza prywatnego — wystarczy sama znajomość numeru certyfikatu. Jest to podatność krytyczna, ponieważ całkowicie podważa mechanizm uwierzytelniania dwuskładnikowego opartego na kartach chipowych.

A vulnerability has been identified in SIPORT MP (All versions < 3.2.1). Vulnerable versions of the device could allow an authenticated attacker to impersonate other users of the system and perform (potentially administrative) actions on behalf of those users if the single sign-on feature ("Allow logon without password") is enabled.

Sparx Enterprise Architect software has a security feature that limits user's actions to those specified in the role. An authenticated attacker can modify the Enterprise Architect client behavior (e.g. using a debugger) and log in as any other user or administrator - then it is possible to do every possible change to the repository. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 17.1 and below were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

NMIS/BioDose V22.02 and previous versions rely on a common SQL Server user account to access data in the database. User access in the client application is restricted by a password authentication check in the client software but the underlying database connection always has access. The latest version of NMIS/BioDose introduces an option to use Windows user authentication with the database, which would restrict this database connection.

mpGabinet performs client-side authentication. An attacker with access to any application instance connected to the backend server can bypass the login verification process by manipulating the application binary and authenticate as an arbitrary user. This issue affects mpGabinet version 23.12.19 and below.

The Restaurant Brands International (RBI) assistant platform through 2025-09-06 relies on client-side authentication for use of the diagnostic screen.

Use of client-side authentication issue exists in CHOCO TEI WATCHER mini (IB-MCT001) all versions. If this issue is exploited, a remote attacker may obtain the product login password without authentication.

MUSASI version 3 contains an issue with use of client-side authentication. If this vulnerability is exploited, other users' credential and sensitive information may be retrieved.

An issue in Flipsnack v.18/03/2024 allows a local attacker to obtain sensitive information via the reader.gz.js file.

Rockwell Automation MicroLogix 1400 Controllers Series B v21.001 and prior, Series A, all versions, MicroLogix 1100 Controller, all versions, RSLogix 500 Software v12.001 and prior, A remote, unauthenticated attacker can send a request from the RSLogix 500 software to the victim’s MicroLogix controller. The controller will then respond to the client with used password values to authenticate the user on the client-side. This method of authentication may allow an attacker to bypass authentication altogether, disclose sensitive information, or leak credentials.

Fresenius Kabi Vigilant Software Suite (Mastermed Dashboard) version 2.0.1.3 allows user input to be validated on the client side without authentication by the server. The server should not rely on the correctness of the data because users might not support or block JavaScript or intentionally bypass the client-side checks. An attacker with knowledge of the service user could circumvent the client-side control and login with service privileges.

In SOOIL Developments Co., Ltd Diabecare RS, AnyDana-i and AnyDana-A, a client-side control vulnerability in the insulin pump and its AnyDana-i and AnyDana-A mobile applications allows physically proximate attackers to bypass user authentication checks via Bluetooth Low Energy.

The cloud service used by ECOVACS robot lawnmowers and vacuums allows authenticated attackers to bypass the PIN entry required to access the live video feed.
