9) Unchecked Return Value (CVE-ID: CVE-2021-0114)
The vulnerability allows a local administrator to escalate privileges on the system.
The vulnerability exists due to unchecked return value in the firmware, which leads to security restrictions bypass and privilege escalation.
10) NULL pointer dereference (CVE-ID: CVE-2021-0111)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a NULL pointer dereference error in the firmware. A local administrator can pass specially crafted data to the application and gain elevated privileges on the system.
11) Unchecked Return Value (CVE-ID: CVE-2021-0107)
The vulnerability allows a local administrator to escalate privileges on the system.
The vulnerability exists due to unchecked return value in the firmware, which leads to security restrictions bypass and privilege escalation.
12) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2021-0103)
The vulnerability allows a local administrator to escalate privileges on the system.
The vulnerability exists due to insufficient control flow management in the firmware, which leads to security restrictions bypass and privilege escalation.
13) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2021-0099)
The vulnerability allows a local administrator to escalate privileges on the system.
The vulnerability exists due to insufficient control flow management in the firmware, which leads to security restrictions bypass and privilege escalation.
14) Improper access control (CVE-ID: CVE-2021-0092)
The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in the firmware. A local administrator can bypass implemented security restrictions and perform a denial of service (DoS) attack.
15) Improper isolation or compartmentalization (CVE-ID: CVE-2021-0060)
The vulnerability allows a local attacker to escalate privileges on the system.
The vulnerability exists due to insufficient compartmentalization in HECI subsystem for the Intel(R) SPS. An attacker with physical access to the system can execute arbitrary code with elevated privileges.
16) Improper locking (CVE-ID: CVE-2021-0147)
The vulnerability allows a local user to perform a denial of service attack (DoS) on the target system.
The vulnerability exists due to double-locking error. An authenticated local user can exploit this vulnerability to cause a deadlock, resulting in a denial of service condition.
17) Improper Initialization (CVE-ID: CVE-2021-0119)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper initialization in the firmware. An administrator with physical access can gain elevated privileges on the target system.
18) Improper access control (CVE-ID: CVE-2021-0091)
The vulnerability allows a local attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in the firmware. A local attacker can bypass implemented security restrictions and gain elevated privileges on the system.
19) Heap-based buffer overflow (CVE-ID: CVE-2021-28211)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the LzmaUefiDecompressGetInfo() function. A local user can run a specially crafted program to trigger a heap-based buffer overflow and execute arbitrary code with elevated privileges.
20) Uncontrolled Recursion (CVE-ID: CVE-2021-28210)
The vulnerability allows a local user to execute arbitrary code on the target system.
The vulnerability exists due to an unlimited recursion in DxeCore. A local user can execute arbitrary code on the target system.
21) NULL pointer dereference (CVE-ID: CVE-2019-14584)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a NULL pointer dereference error. A local user can run a specially crafted program to escalate privileges on the system.
22) Out-of-bounds read (CVE-ID: CVE-2021-3712)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when processing ASN.1 strings related to a confusion with NULL termination of strings in array. A remote attacker can pass specially crafted data to the application to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.
23) Input validation error (CVE-ID: CVE-2022-24423)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause resource exhaustion in the webserver, resulting in a denial of service condition.
