CVE-2021-27383
HighCVSS 7.5Summary
Zidentyfikowano podatność w panelach SIMATIC HMI Comfort Outdoor oraz KTP Mobile, a także w systemie SIMATIC WinCC Runtime Advanced oraz różnych wersjach SINAMICS. Problem dotyczy wycieku pamięci w serwerze Tight encoder SmartVNC, co może prowadzić do stanu Denial-of-Service.
Risk Assessment
Podatność ta może prowadzić do zakłócenia działania systemów HMI oraz urządzeń SINAMICS, co w konsekwencji może wpłynąć na ciągłość operacyjną organizacji.
Recommendation
Zaleca się aktualizację wszystkich wymienionych produktów do wersji, które zawierają poprawki bezpieczeństwa, aby zminimalizować ryzyko wystąpienia ataku Denial-of-Service.

- CVE-2026-102268Critical
PyJWT is a Python implementation of JSON Web Token standards. Prior to version 2.14.0, is_pem_format in jwt/utils.py does not recognize every PEM representation accepted by the cryptography loader. When an application mixes HMAC and asymmetric algorithms and supplies a mutated public-key PEM as raw key bytes, HMACAlgorithm.prepare_key treats the unrecognized asymmetric public key as an HMAC secret. An attacker who knows the public key can forge authenticated HMAC tokens. This issue is fixed in version 2.14.0.
