|
Severity |
CVSS 3.0 Score |
Impact |
|---|---|---|
|
Low |
0.1 - 3.9 |
A vulnerability where scope and impact of exploitation is restricted and the ability to exploit is extremely difficult. |
|
Medium |
4.0 - 6.9 |
A vulnerability where exploitation is mitigated by factors such as difficulty to exploit, default configuration or ease of identification. |
|
High |
7.0 - 8.9 |
A vulnerability, which if exploited, would directly impact the confidentiality, integrity or availability of user’s data or processing resources. |
|
Critical |
9.0 - 10 |
A vulnerability, which if exploited, would allow remote execution of malicious code without user action. |
Applications and Services that utilize the FBX-SDK Ver. 2020.0 or earlier can be impacted by buffer overflow, type confusion, use-after-free, integer overflow, NULL pointer dereference, and heap overflow vulnerabilities.
The details of the vulnerabilities are as follows:
1) CVE-2020-7080: A user may be tricked into opening a malicious FBX file which may exploit a buffer overflow vulnerability in FBX’s SDK causing it to run arbitrary code on the system.
2) CVE-2020-7081: A user may be tricked into opening a malicious FBX file which may exploit a type confusion vulnerability in FBX’s SDK causing it to read/write out-of-bounds memory location or run arbitrary code on the system or lead to denial-of-service.
3) CVE-2020-7082: A user may be tricked into opening a malicious FBX file which may exploit a use-after-free vulnerability in FBX's SDK causing the application to reference a memory location controlled by an unauthorized third party, thereby running arbitrary code on the system.
4) CVE-2020-7083: The user may be tricked into opening a malicious FBX file which may exploit an integer overflow vulnerability in FBX's SDK causing the application to crash leading to a denial of service.
5) CVE-2020-7084: The user may be tricked into opening a malicious FBX file which may exploit a Null Pointer Dereference vulnerability in FBX's SDK causing the application to crash leading to a denial of service.
6) CVE-2020-7085: The user may be tricked into opening a malicious FBX file which would invoke the heap overflow vulnerable FBX parser to obtain a limited code execution by altering certain values in a FBX file, causing the application to run arbitrary code on the system.
