Nutanix AHV : Multiple Vulnerabilities (NXSA-AHV-20220304.423)
critical Nessus Plugin ID 206795
Language:
Synopsis
The Nutanix AHV host is affected by multiple vulnerabilities .Description
The version of AHV installed on the remote host is prior to 20220304.423. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20220304.423 advisory.- An issue in the urllib.parse component of Python before 3.11.4 allows attackers to bypass blocklisting methods by supplying a URL that starts with blank characters. (CVE-2023-24329)
- There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName.
X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or enact a denial of service. 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. (CVE-2023-0286)
- An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory writes via PKCS 12 Safe Bag attributes being mishandled. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8. (CVE-2023-0767)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
