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.

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.
