Een niet-geauthenticeerde externe aanvaller kan hierdoor willekeurige bestanden schrijven naar het onderliggende besturingssysteem. Misbruik van deze kwetsbaarheid kan leiden tot het uitvoeren van commando's met rootrechten, wat de systeemintegriteit beïnvloedt.\n\nCisco meldt bekend te zijn met actief misbruik en heeft Indicators of Compromise en uitgebreide achtergrondinformatie gedeeld.\n\nOp dit moment is (nog) geen Proof-of-Concept-code (PoC) of exploitcode bekend, maar door de aard van de kwetsbaarheid is het aannemelijk dat op korte termijn een PoC of exploit publiek beschikbaar komt. Het NCSC verwacht daarom een toename in scanverkeer en pogingen tot misbruik.",
