- Prioriteit
- Normaal
- Betreft
- Kwetsbaarheden verholpen in DrayTek VigorAP
Kenmerken
- Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
- Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
Omschrijving
DrayTek heeft meerdere kwetsbaarheden verholpen in de VigorAP productlijn.
De kwetsbaarheden bevinden zich in verschillende functies en componenten van de DrayTek VigorAP apparaten, waaronder tr069TestInform, ExportSettings, setLan, setcamset, mesh_start_speed_test, InquierTime, apautotest, upload_settings.cgi en dray_apm. Deze kwetsbaarheden maken het mogelijk voor aanvallers met geldige authenticatie om via onvoldoende inputvalidatie en filtering willekeurige commando's uit te voeren met root-privileges. Daarnaast is er sprake van buffer overflow kwetsbaarheden in de setLan en apautotest functies, waarbij door het versturen van speciaal vervaardigde input een denial of service kan worden veroorzaakt of willekeurige code kan worden uitgevoerd. Exploitatie van deze kwetsbaarheden kan leiden tot volledige systeemcompromittering binnen de context van de root gebruiker. De kwetsbaarheden zijn specifiek van toepassing op meerdere modellen binnen de DrayTek VigorAP productlijn.
Oplossingen
DrayTek heeft updates uitgebracht om de kwetsbaarheden in de VigorAP apparaten te verhelpen. Zie bijgevoegde referenties voor meer informatie.
