5) Security features bypass

EUVDB-ID: #VU70457

Risk: Medium

CVE-ID: CVE-2022-43551

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The vulnerability allows an attacker to gain access to sensitive information.

The vulnerability exists in the way curl handles IDN characters in hostnames. The HSTS mechanism could be bypassed if the hostname in the given URL first uses IDN characters that get replaced to ASCII counterparts as part of the IDN conversion. Then in a subsequent request it does not detect the HSTS state and makes a clear text transfer.

Risk: High

CVE-ID: CVE-2023-0286

CWE-ID: CWE-843 - Type confusion

Exploit availability: No

Description

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

The vulnerability exists due to a type confusion error related to X.400 address processing inside an X.509 GeneralName. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and perform a denial of service (DoS) attack or read memory contents.

In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.
