CWE-ID: CWE-117 - Improper Output Neutralization for Logs

Exploit availability: No

Description

The vulnerability allows a remote attacker to manipulate data in log files.

The vulnerability exists due to improper input validation during WebAuthn authentication or registration. A remote attacker can manipulate data in log files when using the WebAuthn authentication mode.

Mitigation

Install updates from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

How the attacker can exploit this vulnerability?

The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Integer overflow

EUVDB-ID: #VU63553

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-43618

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to integer overflow in mpz/inp_raw.c. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.

Mitigation

3) Expected behavior violation

EUVDB-ID: #VU76238

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-28322

CWE-ID: CWE-440 - Expected Behavior Violation

Exploit availability: No

Description

The 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.

Mitigation

Install updates from vendor's website.

4) External control of file name or path

EUVDB-ID: #VU81863

Risk: Low

CVSSv3.1: 2.3 [CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

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.

Mitigation

Install updates from vendor's website.

5) 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 updates from vendor's website.
