The version of cloud-hypervisor-cvm / nodejs18 installed on the remote CBL Mariner 2.0 host is prior to tested version.
It is, therefore, affected by a vulnerability as referenced in the CVE-2023-5363 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- Issue summary: A bug has been identified in the processing of key and initialisation vector (IV) lengths.
This can lead to potential truncation or overruns during the initialisation of some symmetric ciphers.
Impact summary: A truncation in the IV can result in non-uniqueness, which could result in loss of
confidentiality for some cipher modes. When calling EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() or
EVP_CipherInit_ex2() the provided OSSL_PARAM array is processed after the key and IV have been
established. Any alterations to the key length, via the keylen parameter or the IV length, via the
ivlen parameter, within the OSSL_PARAM array will not take effect as intended, potentially causing
truncation or overreading of these values. The following ciphers and cipher modes are impacted: RC2, RC4,
RC5, CCM, GCM and OCB. For the CCM, GCM and OCB cipher modes, truncation of the IV can result in loss of
confidentiality. For example, when following NIST's SP 800-38D section 8.2.1 guidance for constructing a
deterministic IV for AES in GCM mode, truncation of the counter portion could lead to IV reuse. Both
truncations and overruns of the key and overruns of the IV will produce incorrect results and could, in
some cases, trigger a memory exception. However, these issues are not currently assessed as security
critical. Changing the key and/or IV lengths is not considered to be a common operation and the vulnerable
API was recently introduced. Furthermore it is likely that application developers will have spotted this
problem during testing since decryption would fail unless both peers in the communication were similarly
vulnerable. For these reasons we expect the probability of an application being vulnerable to this to be
quite low. However if an application is vulnerable then this issue is considered very serious. For these
reasons we have assessed this issue as Moderate severity overall. The OpenSSL SSL/TLS implementation is
not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this because the
issue lies outside of the FIPS provider boundary. OpenSSL 3.1 and 3.0 are vulnerable to this issue.
