Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21868)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data in the ObjectManager.plugin Project.get_MissingTypes() functionality. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

2) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21863)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data in the ComponentModel Profile.FromFile() functionality. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

3) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21865)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data in the PackageManagement.plugin ExtensionMethods.Clone() functionality. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

4) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21866)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data in the ObjectManager.plugin ProfileInformation.ProfileData functionality. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

5) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21867)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data in the ObjectManager.plugin ObjectStream.ProfileByteArray functionality. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

6) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21864)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data in the ComponentModel ComponentManager.StartupCultureSettings functionality. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

7) Deserialization of Untrusted Data (CVE-ID: CVE-2021-21869)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data in the Engine.plugin ProfileInformation ProfileData functionality. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
