Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) 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
DescriptionThe 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.
Install updates from vendor's website.
Vulnerable software versionscURL: 8.5.0 - 8.6.0

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

No. We are not aware of malware exploiting this vulnerability.
2) 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
DescriptionThe 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.

3) 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
DescriptionThe 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.
