Feiten
Palo Alto Networks heeft een kwetsbaarheid verholpen in PAN-OS.
Interpretaties
De kwetsbaarheid bevindt zich in de manier waarop PAN-OS omgaat met bepaalde verzoeken. Ongeauthenticeerde aanvallers kunnen een Denial-of-Service (DoS) veroorzaken door herhaaldelijk verzoeken te sturen, wat ertoe kan leiden dat de firewall in onderhoudsmodus gaat en daarmee de normale werking verstoord raakt.
Oplossingen
Palo Alto Networks heeft updates uitgebracht om de kwetsbaarheid te verhelpen. Zie bijgevoegde referenties voor meer informatie.
Kans
medium
Schade
high
CWE-754
