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

The vulnerability exists due to improper management of internal resources within the application when processing multiple connection attempts with an 'unknownProtocol'. A remote attacker can initiate multiple connections with the server, which will trigger a leak of file descriptors and result in a denial of service (DoS) condition.

2) DNS rebinding

EUVDB-ID: #VU50955

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-22884

CWE-ID: CWE-350 - Reliance on Reverse DNS Resolution for a Security-Critical Action

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform DNS rebinding attack.

The vulnerability exists due to the application whitelist includes the “localhost6” name. When “localhost6” is not present in /etc/hosts, it is treated an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the “localhost6” domain.

Mitigation

Install updates from vendor's website.
