Omschrijving
Ivanti heeft kwetsbaarheden verholpen in Connect Secure, Policy Secure en ZTA Gateways.
De kwetsbaarheden omvatten een buffer over-read en een heap-gebaseerde buffer overflow, die beide kunnen worden misbruikt door remote ongeauthenticeerde aanvallers om een Denial-of-Service (DoS) te veroorzaken. Daarnaast is er een probleem met de onjuiste behandeling van symbolische links, waardoor lokale geauthenticeerde aanvallers toegang kunnen krijgen tot willekeurige bestanden op de schijf, wat kan leiden tot ongeautoriseerde toegang tot gevoelige informatie.
Oplossingen
Ivanti heeft patches uitgebracht om deze kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
