23) Improper input validation

EUVDB-ID: #VU75270

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-21912

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

24) Security features bypass

EUVDB-ID: #VU70457

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-43551

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The vulnerability allows an attacker to gain access to sensitive information.

The vulnerability exists in the way curl handles IDN characters in hostnames. The HSTS mechanism could be bypassed if the hostname in the given URL first uses IDN characters that get replaced to ASCII counterparts as part of the IDN conversion. Then in a subsequent request it does not detect the HSTS state and makes a clear text transfer.

Mitigation

Install update from vendor's website.
