2) Improper certificate validation
EUVDB-ID: #VU76237
Risk: Medium
CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-28321
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 when matching wildcards in TLS certificates for IDN names. A remote attacker crate a specially crafted certificate that will be considered trusted by the library.
Successful exploitation of the vulnerability requires that curl is built to use OpenSSL, Schannel or Gskit.
MitigationUpdate the affected package curl to the latest version.

3) Expected behavior violation
EUVDB-ID: #VU76238
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-2023-28322
CWE-ID:
CWE-440 - Expected Behavior Violation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a logic error when sending HTTP POST and PUT requests using the same handle. The libcurl can erroneously use the read callback (CURLOPT_READFUNCTION) to ask for data to send, even when the CURLOPT_POSTFIELDS option has been set, if the same handle previously was used to issue a PUT request which used that callback. As a result, the application can misbehave and either send off the wrong data or use memory after free or similar in the second transfer.
MitigationUpdate the affected package curl to the latest version.
