Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU31753
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-3323
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the web-based management interface. A remote attacker can send a specially crafted HTTP request, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationInstall updates from vendor's website.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected device in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Improper Authorization
EUVDB-ID: #VU31754
Risk: Medium
CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-3150
CWE-ID:
CWE-285 - Improper Authorization
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authorization process.
The vulnerability exists due to improper authorization of an HTTP request. A remote attacker can access a specific URI on the web-based management interface of the router, but only after any valid user has opened a specific file on the device since the last reboot, and view sensitive information on the target device.
