gnutls: gnutls: Authentication Bypass via NUL Character in Username
Einstufung nach Quelle
Trivys eigenes Label ist CRITICAL. Kritisch laut NVD, Photon OS. Niedriger laut Red Hat (hoch), AlmaLinux (hoch), Amazon (hoch), Oracle (hoch), Rocky Linux (hoch), Azure Linux (mittel), Ubuntu (mittel).
Beschreibung
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.
