2) Information disclosure

EUVDB-ID: #VU83900

Risk: Low

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

Description

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.

Mitigation

Install update from vendor's website.

3) Missing Encryption of Sensitive Data

EUVDB-ID: #VU83899

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-46219

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

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.

4) Out-of-bounds read

EUVDB-ID: #VU86807

Risk: Low

CVSSv3.1: 3.9 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-25629

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description
