CVE-2023-38546

Public on 2023-10-11
Modified on 2024-02-07
Description

An issue was found in libcurl which allows cookies to be inserted into a running program if specific conditions are met. The libcurl provided function, curl_easy_duphandle(), is used to duplicate the easy_handle associated with a transfer. If a duplicated transfer's easy_handle has cookies enabled when it is duplicated, the cookie-enabled state is cloned but the actual cookies are not. If the source easy_handle didn't read cookies from disk, the cloned easy_handle will attempt to read cookies from a file named 'none' in the local directory, potentially allowing arbitrary cookies to be loaded.
