CVE-2021-23892
HighSummary
Podatność CVE-2021-23892 dotyczy warunków wyścigu TOCTOU podczas instalacji Endpoint Security for Linux Threat Prevention i Firewall, co pozwala lokalnemu użytkownikowi na eskalację uprawnień do poziomu administratora. Wykorzystując tę lukę, można uruchomić dowolny kod poprzez niebezpieczne użycie przewidywalnych lokalizacji plików tymczasowych.
Risk Assessment
Organizacja narażona jest na ryzyko nieautoryzowanego dostępu do systemów oraz możliwość uruchomienia złośliwego kodu, co może prowadzić do poważnych naruszeń bezpieczeństwa. Eskalacja uprawnień może umożliwić atakującym pełną kontrolę nad systemem.
Recommendation
Zaleca się aktualizację oprogramowania Endpoint Security for Linux do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto przeprowadzić audyt uprawnień użytkowników oraz monitorować systemy pod kątem nieautoryzowanych działań.

- 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.

Original NVD description (English source)
By exploiting a time of check to time of use (TOCTOU) race condition during the Endpoint Security for Linux Threat Prevention and Firewall (ENSL TP/FW) installation process, a local user can perform a privilege escalation attack to obtain administrator privileges for the purpose of executing arbitrary code through insecure use of predictable temporary file locations.
