Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU63007
Risk: Low
CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
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 updates from vendor's website.

2) Infinite loop
EUVDB-ID: #VU63008
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-27781
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when handling requests with the CURLOPT_CERTINFO option. A remote attacker can consume all available system resources and cause denial of service conditions.

3) Incorrect Implementation of Authentication Algorithm
EUVDB-ID: #VU63009
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-27782
CWE-ID:
CWE-303 - Incorrect Implementation of Authentication Algorithm
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the way libcurl handles previously used connections in a connection pool for subsequent transfers. Several TLS and SSH settings were left out from the configuration match checks, resulting in erroneous matches for different resources. As a result, libcurl can send authentication string from one resource to another, exposing credentials to a third-party.
