All disputes related to or arising from the use of this advisory will be submitted to the competent court in The Hague. This choice of means also applies to the court in summary proceedings.
Feiten
Synacor heeft kwetsbaarheden verholpen in Zimbra Collaboration.
Interpretaties
Door middel van het versturen van een speciaal geprepareerde e-mail naar de SMTP server kan direct code executie worden verkregen op de Zimbra server die bijvoorbeeld gebruikt kan worden om een webshell te plaatsen. Onderzoekers hebben Proof-of-Concept-code gepubliceerd, waarmee de kwetsbaarheid met kenmerk CVE-2024-45519 kan worden aangetoond. Er is een exploit beschikbaar en er zijn signalen van actief misbruik.
Oplossingen
UPDATE: Het NCSC heeft op Github een tool beschikbaar gesteld die gebruikt kan worden om een eventuele webshell die middels deze kwetsbaarheid is geplaatst te detecteren. Synacor heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie en de link naar de scantool op Github.
