Title

Out-of-bounds read vulnerability

Summary

VMware ESX, Workstation, and Fusion contain an out-of-bounds read vulnerability. A malicious actor with VM deployment privileges could trigger an out-of-bounds read, potentially leading to information disclosure or more likely a Denial-of-Service (DoS) condition of the host process. On Workstation and Fusion, the impact of this vulnerability is restricted to information disclosure.

Severity

7.6 (High)

Kwetsbaarheden verholpen in VMware producten

Notes

Feiten: VMware heeft kwetsbaarheden verholpen in VMware vCenter en VMware ESX producten.

Interpretaties: VMware vCenter bevat een kritieke authentication-bypass kwetsbaarheid in de Directory Service met kenmerk CVE-2026-59309. Deze kwetsbaarheid stelt een kwaadwillende met netwerktoegang tot VMware vCenter in staat deze kwetsbaarheid te misbruiken om de authenticatie te omzeilen en ongeautoriseerde toegang tot het systeem te verkrijgen. Daarnaast bevat VMware vCenter ook een kritieke directory-traversal kwetsbaarheid in de Syslog server met kenmerk CVE-2026-59310. Deze kwetsbaarheid kan een kwaadwillende in staat stellen willekeurige code uit te voeren, waardoor mogelijk bestands- en directorypaden kunnen worden gemanipuleerd en toegang kan worden verkregen tot bestanden buiten de bedoelde Syslog-directory. VMware ESX bevat een kritieke out-of-bounds write kwetsbaarheid in de VMXNET3 virtuele netwerkadapter met kenmerk CVE-2026-47876. Deze kwetsbaarheid stelt een kwaadwillende met lokale beheerdersrechten op een virtuele machine met een VMXNET3 virtuele netwerkadapter in staat, code uit te voeren op de onderliggende host. Dit maakt het voor een kwaadwillende mogelijk, data buiten de bedoelde geheugenlimieten kan schrijven, wat kan leiden tot geheugenbeschadiging en onvoorspelbaar gedrag of compromittering van het virtuele systeem. Virtuele netwerkadapters die geen gebruikmaken van VMXNET3 zijn niet kwetsbaar. In VMware ESX, Workstation en Fusion bevatten ook een out-of-bounds read kwetsbaarheid met kenmerk CVE-2026-41703. Misbruik van deze kwetsbaarheid die kan resulteren in onbedoelde toegang tot geheugen buiten de toegewezen buffer, wat kan leiden tot informatielekken of systeeminstabiliteit binnen virtuele omgevingen. Daarnaast bevat VMware ESX een kwetsbaarheid met kenmerk CVE-2026-41709 door onvoldoende logging. Een kwaadwillende beheerder kan deze kwetsbaarheid misbruiken om bepaalde acties uit te voeren die niet in de logbestanden worden geregistreerd. Het is goed gebruik om toegang tot ESX en vCenter uitsluitend beschikbaar te stellen vanuit een gescheiden beheeromgeving waarin alleen geautoriseerde beheerders toegang hebben. Deze beheerinterfaces dienen niet rechtstreeks vanaf internet of externe netwerken toegankelijk te zijn.

Oplossingen: VMware heeft updates uitgebracht om de kwetsbaarheden in VMware vCenter, ESX, Workstation en Fusion te verhelpen. Zie bijgevoegde referenties voor meer informatie.
