2) Information disclosure

EUVDB-ID: #VU62644

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-27776

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

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

The vulnerability exists due to curl can leak authentication or cookie header data during HTTP redirects to the same host but another port number. When asked to send custom headers or cookies in its HTTP requests, curl sends that set of headers only to the host which name is used in the initial URL, so that redirects to other hosts will make curl send the data to those. However, due to a flawed check, curl wrongly also sends that same set of headers to the hosts that are identical to the first one but use a different port number or URL scheme.

The vulnerability exists due to an incomplete fix for #VU10224 (CVE-2018-1000007).

EUVDB-ID: #VU62643

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-27775

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

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

The vulnerability exists due to improper management of internal resources when handling IPv6 protocol. Due to errors in the logic, the config matching function did not take the IPv6 address zone id into account which could lead to libcurl reusing the wrong connection when one transfer uses a zone id and a subsequent transfer uses another (or no) zone id.

6) Improper Authentication

EUVDB-ID: #VU62640

Risk: Medium

CVSSv4.0: 6.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-22576

CWE-ID: CWE-287 - Improper Authentication

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error when re-using OAUTH2 connections for SASL-enabled protocols, such as SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only). libcurl may reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. As a result, a connection that is successfully created and authenticated with a user name + OAUTH2 bearer can subsequently be erroneously reused even for user + [other OAUTH2 bearer], even though that might not even be a valid bearer.

A remote attacker can exploit this vulnerability against applications intended for use in multi-user environments to bypass authentication and gain unauthorized access to victim's accounts.
