The vulnerability allows a local user to compromise vulnerable system.

The vulnerability exists due to a use-after-free error. A local administrator can obtain a higher privilege and compromise the service.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


2) Use-after-free (CVE-ID: CVE-2020-9105)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to use-after-free error. A local administrator can trigger memory corruption and escalate privileges on the target device.

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition. A local attacker can send a specially crafted request, trigger out-of-bounds read error and read contents of memory on the system.


6) Information disclosure (CVE-ID: CVE-2020-9110)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local attacker to gain access to potentially sensitive information.

The vulnerability exists due to excessive data output by the application. A local attacker can gain unauthorized access to sensitive information on the system.


7) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-9112)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local attacker to escalate privileges on the system.
