EUVDB-ID: #VU71992
Risk: High
CVSSv4.0: 6.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2023-0286
CWE-ID:
CWE-843 - Type confusion
Exploit availability: No
DescriptionThe 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.
