Technical details
A path traversal vulnerability exists in Broadcom VMware vCenter that enables unauthenticated or low-privileged attackers with network access to traverse the filesystem and access restricted files or resources. The vulnerability allows an attacker to break out of intended directory restrictions by using path traversal sequences (such as "../"), potentially leading to arbitrary code execution on the vCenter server. The attack requires network reachability to vCenter but does not appear to require prior authentication. The vulnerability has been confirmed as actively exploited in the wild, indicating that real-world threat actors have weaponized this flaw. A patch or upgrade is recommended to remediate this critical issue.
