CVE-2017-4921
HighSummary
VMware vCenter Server (6.5 prior to 6.5 U1) contains an insecure library loading issue due to the unsafe use of the LD_LIBRARY_PATH variable. Successful exploitation of this vulnerability may allow unprivileged host users to load a shared library, potentially leading to privilege escalation.
Risk Assessment
The organization may be at risk of privilege escalation by unprivileged users, which could lead to unauthorized access to systems and data.
Recommendation
It is recommended to update VMware vCenter Server to version 6.5 U1 or later to mitigate this vulnerability. Additionally, review the configuration of the LD_LIBRARY_PATH variable to enhance security.
