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.

CVSSv3.1: 2.3 [CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-38546
CWE-ID:
CWE-73 - External Control of File Name or Path
Exploit availability: No
DescriptionThe vulnerability allows an attacker to inject arbitrary cookies into request.
The vulnerability exists due to the way cookies are handled by libcurl. If a transfer has cookies enabled when the handle is duplicated, the
cookie-enable state is also cloned - but without cloning the actual
cookies. If the source handle did not read any cookies from a specific
file on disk, the cloned version of the handle would instead store the
file name as none
(using the four ASCII letters, no quotes).
none
- if such a file exists and is readable in the current directory of the program using libcurl.

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-46218
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to an error in curl that allows a malicious HTTP server to set "super cookies" that are then passed back to more origins than what is otherwise allowed or possible. A remote attacker can force curl to send such cookie to different and unrelated sites and domains.
