VMware vCenter Server: ASP.NET Misconfiguration: Use of Identity Impersonation
CVE-2024-37081 is a high-severity ASP.NET misconfiguration: use of identity impersonation vulnerability in VMware vCenter Server, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions 8.0 U2d, 7.0 U3r as the first without the flaw, so updating VMware vCenter Server to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 4.99% chance of exploitation within 30 days, which is in the top 7.65% of all scored CVEs.
High severity with no evidence of exploitation so far.
