Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2021-20700)

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

The vulnerability exists due to a boundary error in the Disk Agent. A remote attacker can send a specially crafted packet, trigger memory corruption and execute arbitrary code on the target system.

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


2) Buffer overflow (CVE-ID: CVE-2021-20701)

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

The vulnerability exists due to a boundary error in the Disk Agent. A remote attacker can send a specially crafted packet, trigger memory corruption and execute arbitrary code on the target system.

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


3) Buffer overflow (CVE-ID: CVE-2021-20702)

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

The vulnerability exists due to a boundary error in the Transaction Server. A remote attacker can send a specially crafted packet, trigger memory corruption and execute arbitrary code on the target system.

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


4) Buffer overflow (CVE-ID: CVE-2021-20703)

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

The vulnerability exists due to a boundary error in the Transaction Server. A remote attacker can send a specially crafted packet, trigger memory corruption and execute arbitrary code on the target system.

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


5) Buffer overflow (CVE-ID: CVE-2021-20704)

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

The vulnerability exists due to a boundary error in the compatible API with previous versions (Ver 8.0 and earlier). A remote attacker can send a specially crafted packet, trigger memory corruption and execute arbitrary code on the target system.

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


6) Input validation error (CVE-ID: CVE-2021-20705)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to insufficient validation of user-supplied input in the WebManager. A remote attacker can pass specially crafted input to the application and upload arbitrary file on the target system.


7) Input validation error (CVE-ID: CVE-2021-20706)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to insufficient validation of user-supplied input in the WebManager. A remote attacker can pass specially crafted input to the application and upload arbitrary file on the target system.


8) Input validation error (CVE-ID: CVE-2021-20707)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to insufficient validation of user-supplied input in the Transaction Server. A remote attacker can pass specially crafted input to the application and read arbitrary file on the target system.
