Description

This security bulletin contains information about 2 vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2023-46218)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The 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.


2) Missing Encryption of Sensitive Data (CVE-ID: CVE-2023-46219)

CWE-ID: CWE-311 - Missing Encryption of Sensitive Data

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to an error when handling HSTS long file names. When saving HSTS data to an excessively long file name, curl can end up removing all contents from the file, making subsequent requests using that file unaware of the HSTS status they should otherwise use. As a result, a remote attacker can perform MitM attack.
