3) External control of file name or path

EUVDB-ID: #VU81863

Risk: Low

CVSSv4.0: 0.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-38546

CWE-ID: CWE-73 - External Control of File Name or Path

Exploit availability: No

Description

The 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).

Subsequent use of the cloned handle that does not explicitly set a source to load cookies from would then inadvertently load cookies from a file named none - if such a file exists and is readable in the current directory of the program using libcurl.

CVE-ID: CVE-2023-38545

CWE-ID: CWE-122 - Heap-based Buffer Overflow
