Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2020-3992)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the OpenSLP service. A remote attacker can can send specially crafted SLP message to port 427/udp, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
2) Out-of-bounds read (CVE-ID: CVE-2020-3981)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition due to a time-of-check time-of-use issue in ACPI device within the implementation of the BDOOR_CMD_PATCH_ACPI_TABLES command. A remote administrator on a guest OS can run a specially crafted program to read memory from the vmx process.
3) Out-of-bounds write (CVE-ID: CVE-2020-3982)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error caused by a time-of-check time-of-use issue in ACPI device within the implementation of the BDOOR_CMD_PATCH_ACPI_TABLES command. A remote administrator on the guest OS can run a specially crafted program to trigger a heap-based buffer overflow and crash the system or execute arbitrary code on the hypervisor.
4) Memory leak (CVE-ID: CVE-2020-3995)
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak within the VMCI host driver. A remote attacker can force the application to leak memory and perform denial of service attack.
5) Use-after-free (CVE-ID: CVE-2020-4004)
The vulnerability allows a local user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the XHCI USB controller. A local administrator can execute arbitrary code as the virtual machine's VMX process running on the host
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-4005)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to application does not properly impose security restrictions, which leads to security restrictions bypass and privilege escalation.
7) Input validation error (CVE-ID: CVE-2021-21972)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input in vSphere Client. A remote non-authenticated attacker can send a specially crafted HTTP request to port 443/tcp and execute arbitrary code on the system.
8) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2021-21973)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in vSphere Client. A remote non-authenticated attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
