L'organisation OISF (Open Information Security Foundation) a publi\u00e9 des mises \u00e0 jour correctrices pour les syst\u00e8mes de d\u00e9tection et de pr\u00e9vention des intrusions r\u00e9seau Suricata 6.0.3 et 5.0.7, qui corrigent la vuln\u00e9rabilit\u00e9 CVE-2021-35063, pr\u00e9sentant un niveau de danger \u00e9lev\u00e9. Ce probl\u00e8me permet de contourner tous les analyseurs et v\u00e9rifications de Suricata. <\/p>\n

La vuln\u00e9rabilit\u00e9 r\u00e9sulte de la d\u00e9sactivation de l'analyse de flux pour les paquets avec une valeur ACK non nulle, mais sans le bit ACK d\u00e9fini, ce qui permettait de commencer une session TCP avec un paquet SYN contenant un ACK non nul, dehors de la zone de v\u00e9rification dans Suricata. De tels paquets \u00e9taient identifi\u00e9s comme erron\u00e9s dans Suricata et les gestionnaires renvoyaient un code d'erreur sans analyser le contenu.
