According to the versions of the python-pycryptodome package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
PyCryptodome and pycryptodomex before 3.19.1 allow side-channel leakage for OAEP decryption, exploitable for a Manger attack.(CVE-2023-52323)
Tenable has extracted the preceding description block directly from the EulerOS Virtualization python-pycryptodome security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
