ESXi < 7.0 Reflected Denial of Service

high Nessus Plugin ID 176249


The remote VMware ESXi host is missing a security patch and is affected by a vulnerability.


The remote VMware ESXi host is less than version 7.0 and is affected by a reflected denial of service vulnerability:

- The Service Location Protocol (SLP, RFC 2608) allows an unauthenticated, remote attacker to register arbitrary services. This could allow the attacker to use spoofed UDP traffic to conduct a denial-of-service attack with a significant amplification factor. (CVE-2023-29552)

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


Upgrade to ESXi 7.0 U2c, ESXi 8.0 GA or newer or disable SLP.
