Summary

VMware VMware Fusion (11.x before 11.0.3) contains a security vulnerability due to certain unauthenticated APIs accessible through a web socket. An attacker may exploit this issue by tricking the host user to execute a JavaScript to perform unauthorized functions on the guest machine where VMware Tools is installed. This may further be exploited to execute commands on the guest machines.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Choosing a Message/Channel Identifier on a Public/Multicast Channel
    Attackers aware that more data is being fed into a multicast or public information distribution means can 'select' information bound only for another client, even if the distribution means itself forces users to authenticate in order to connect initially. Doing so allows the attacker to gain access to possibly privileged information, possibly perpetrate other attacks through the distribution means by impersonation. If the channel/message being manipulated is an input rather than output mechanism for the system, (such as a command bus), this style of attack could change its identifier from a less privileged to more so privileged channel or command.
  • Using Unpublished Web Service APIs
    An attacker searches for and invokes Web Services APIs that the target system designers did not intend to be publicly available. If these APIs fail to authenticate requests the attacker may be able to invoke services and/or gain privileges they are not authorized for.
  • Manipulating Writeable Terminal Devices
    This attack exploits terminal devices that allow themselves to be written to by other users. The attacker sends command strings to the target terminal device hoping that the target user will hit enter and thereby execute the malicious command with their privileges. The attacker can send the results (such as copying /etc/passwd) to a known directory and collect once the attack has succeeded.
  • Cross Site Request Forgery (aka Session Riding)
    An attacker crafts malicious web links and distributes them (via web pages, email, etc.), typically in a targeted manner, hoping to induce users to click on the link and execute the malicious action against some third-party application. If successful, the action embedded in the malicious link will be processed and accepted by the targeted application with the users' privilege level. This type of attack leverages the persistence and implicit trust placed in user session cookies by many web applications today. In such an architecture, once the user authenticates to an application and a session cookie is created on the user's system, all following transactions for that session are authenticated using that cookie including potential actions initiated by an attacker and simply "riding" the existing session cookie.

the virtual USB 1.1 UHCI (Universal Host Controller Interface).
Exploitation of these issues requires an attacker to have access to a

allow a guest to execute code on the host.

VMware would like to thank the Fluoroacetate team of Amat Cama and

VMware Workstation and Fusion contain an out-of-bounds write
vulnerability in the e1000 virtual network adapter. This issue may
allow a guest to execute code on the host.

VMware would like to thank security researcher Zhangyanyu of Chaitin
Tech for reporting this issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the identifier CVE-2019-5524 to this issue.

VMware Workstation and Fusion updates address an out-of-bounds write
vulnerability in the e1000 and e1000e virtual network adapters.
Exploitation of this issue may lead to code execution on the host from
the guest but it is more likely to result in a denial of service of the
guest.

VMware would like to thank ZhanluLab working with Trend Micro's Zero
Day Initiative for reporting this issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the identifier CVE-2019-5515 to this issue.
