CVE-2021-22779
CriticalSummary
W podatności CVE-2021-22779 występuje możliwość ominięcia uwierzytelniania poprzez spoofing w EcoStruxure Control Expert oraz powiązanych produktach. Dotyczy to wszystkich wersji przed V15.0 SP1 oraz wersji V15.0 SP1, co może prowadzić do nieautoryzowanego dostępu do kontrolera.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp do systemów kontrolnych, co może skutkować nieautoryzowanym odczytem i zapisem danych. To stwarza poważne zagrożenie dla integralności i bezpieczeństwa operacji przemysłowych.
Recommendation
Zaleca się aktualizację do wersji V15.0 SP1 lub nowszej oraz wdrożenie dodatkowych środków zabezpieczających w celu ochrony przed potencjalnym spoofingiem komunikacji Modbus.

- CVE-2026-53939Critical
In cjose versions 0.6.1 through 0.6.2.5, when encrypting a JWE using AES-CBC-HMAC content-encryption algorithms (A128CBC-HS256, A192CBC-HS384, A256CBC-HS512) with any key-management algorithm that generates a fresh content-encryption key (CEK), the CEK is all zero bytes instead of being randomly generated. The resulting JWE is encrypted and authenticated under a fixed, publicly known key, allowing anyone who obtains the JWE to recover plaintext and forge or modify content. Fixed in 0.6.2.6 by generating CEK from RAND_bytes.
- CVE-2026-53581Critical
OPNsense is a FreeBSD based firewall and routing platform. Prior to version 26.1.9 of opnsense/core and version 26.4_20 of BE/opnsense/core, a path traversal vulnerability in the NTP configuration module allows an attacker to overwrite arbitrary files on the system as the root user. By manipulating the GPS or PPS serial port parameter, an attacker with access to the NTP configuration can escape the intended directory and write user-controlled data to any file.
- CVE-2026-85982Critical
The Auth0 AD/LDAP Connector is vulnerable to stored Cross-Site Scripting (XSS) issues due to improper HTML encoding of data in search results and updater log content displayed in the admin panel. An authenticated user with privileges to modify directory attributes, or a low-privileged local user on the host, could insert script content that executes in an administrator's browser.
Original NVD description (English source)
Authentication Bypass by Spoofing vulnerability exists in EcoStruxure Control Expert (all versions prior to V15.0 SP1, including all versions of Unity Pro), EcoStruxure Control Expert V15.0 SP1, EcoStruxure Process Expert (all versions, including all versions of EcoStruxure Hybrid DCS), SCADAPack RemoteConnect for x70 (all versions), Modicon M580 CPU (all versions - part numbers BMEP* and BMEH*), Modicon M340 CPU (all versions - part numbers BMXP34*), that could cause unauthorized access in read and write mode to the controller by spoofing the Modbus communication between the engineering software and the controller.
