3) Improper check for certificate revocation

EUVDB-ID: #VU85927

Risk: Low

CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-0853

CWE-ID: CWE-299 - Improper Check for Certificate Revocation

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass OCSP verification.

The vulnerability exists due to curl inadvertently keeps the SSL session ID for connections in its cache even when the verify status (OCSP stapling) test has failed. A subsequent transfer to the same hostname will be successful if the session ID cache is still fresh, which leads to skipping the verify status check. As a result, OCSP verification is always successful for all subsequent TLS sessions.

Mitigation

Install update from vendor's website.

Vulnerable software versions

MySQL Cluster: 8.0.16 - 8.3.0

Q & A

Can this vulnerability be exploited remotely?

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

Is there known malware, which exploits this vulnerability?

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

4) Resource exhaustion

EUVDB-ID: #VU81728

Risk: High

CVSSv3.1: 5.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:H/RL:O/RC:C]

CVE-ID: CVE-2023-44487

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

Note, the vulnerability is being actively exploited in the wild.

Mitigation

Install update from vendor's website.
