Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Improper Authentication

EUVDB-ID: #VU54146

Risk: Medium

CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-0133

CWE-ID: CWE-287 - Improper Authentication

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to key exchange without entity authentication. A remote authenticated attacker can bypass authentication process and gain elevated privileges on the system.

Mitigation

Install updates from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote authenticated user via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Improper Resource Shutdown or Release

EUVDB-ID: #VU54147

Risk: Low

CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-0132

CWE-ID: CWE-404 - Improper Resource Shutdown or Release

Exploit availability: No

Description

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to missing release of resource after effective lifetime in an API. A remote administrator can cause a denial of service condition on the target system.

Mitigation

Install updates from vendor's website.
