"According to the versions of the NetworkManager packages installed, the EulerOS installation on the remote host is
affected by the following vulnerabilities :

    A flaw was found in NetworkManager. This local privilege escalation vulnerability exists in
    NetworkManager's dhclient backend when processing malformed Manufacturer Usage Description (MUD) URLs. A
    local user can exploit this flaw to escalate privileges by triggering a script via a crafted MUD URL,
    provided an administrator has explicitly configured NetworkManager to use dhclient. This issue does not
    affect default configurations of NetworkManager.(CVE-2026-10805)

Tenable has extracted the preceding description block directly from the EulerOS NetworkManager security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
