Cleartext transmission of sensitive information in cURL - CVE-2022-42916

Vulnerability identifier: #VU68749

CSH Severity: Medium

CVSS v4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2022-42916

CWE-ID: CWE-319

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to an error when parsing URL with IDN characters that get replaced to ASCII counterparts as part of the IDN conversion. A remote attacker can bypass curl's HSTS check and trick it into using unencrypted HTTP protocol.
