Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU63007
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-27780
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass filters and checks.
The vulnerability exists due to the curl URL parser wrongly accepts percent-encoded URL separators like '/' when decoding the host name part of a URL, making it a different URL using the wrong host name when it is later retrieved. For example, the URL like http://example.com%2F10.0.0.1/, would be allowed by the parser and get transposed into http://example.com/10.0.0.1/.
A remote attacker can bypass various internal filters and checks and force the curl to connect to a wrong web application.
Install update from vendor's website.

2) Cleartext transmission of sensitive information
EUVDB-ID: #VU63011
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-30115
CWE-ID:
CWE-319 - Cleartext Transmission of Sensitive Information
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error in HSTS implementation that can allow curl to continue using HTTP protocol instead of HTTPS if the host name in the given URL used a trailing dot while not using one when it built the HSTS cache. A remote attacker with ability to intercept traffic can obtain potentially sensitive information.
