Ongeauthenticeerde aanvallers kunnen deze kwetsbaarheid misbruiken om ongeautoriseerde code of commando\u0027s uit te voeren door middel van speciaal vervaardigde TCP-verzoeken. Dit kan leiden tot beveiligingsimplicaties, waarbij aanvallers het systeemgedrag kunnen manipuleren en ongeautoriseerde toegang tot gevoelige informatie kunnen verkrijgen.\n\nOnderzoekers hebben recentelijk Proof-of-Concept-code (PoC) uitgebracht, wat het risico op grootschalig misbruik vergroot. Ook zijn er middels publieke bronnen actieve exploitatie pogingen waargenomen op honeypot infrastructuur. \n",
