Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU87846

Risk: Low

CVSSv3.1: 3.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-2004

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exists due to an error when a protocol selection parameter option disables all protocols without adding any. As a result, the default set of protocols would remain in the allowed set due to an error in the logic for removing protocols.

Mitigation

Install updates from vendor's website.

2) Improper Certificate Validation

EUVDB-ID: #VU87848

Risk: Low

CVSSv3.1: 3.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-2379

CWE-ID: CWE-295 - Improper Certificate Validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to improper certificate validation for a QUIC connection under certain conditions, when built to use wolfSSL. A remote attacker can force the application to ignore the certificate and perform MitM attack.

Successful exploitation of the vulnerability requires that the used wolfSSL library was built with the OPENSSL_COMPATIBLE_DEFAULTS symbol set, which is not set for the recommended configure --enable-curl builds.

3) Missing Release of Resource after Effective Lifetime

EUVDB-ID: #VU87850

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-2398

CWE-ID: CWE-772 - Missing Release of Resource after Effective Lifetime

Exploit availability: No

Description

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

The vulnerability exists due to an error when sending HTTP/2 server push responses with an overly large number of headers. A remote attacker can send PUSH_PROMISE frames with an excessive amount of headers to the application, trigger memory leak and perform a denial of service (DoS) attack.

Mitigation

4) Improper validation of certificate with host mismatch

EUVDB-ID: #VU87852

Risk: Medium

CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-2466

CWE-ID: CWE-297 - Improper Validation of Certificate with Host Mismatch

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to libcurl does not check the server certificate of TLS connections done to a host specified as an IP address, when built to use mbedTLS. A remote attacker force the application to completely skip the certificate check and perform MitM attack.

Mitigation
