Detection & IOCsextracted from sources · hover to see the quote
- →An attacker with any valid SCOM login can create a custom dashboard containing a PowerShell widget to execute arbitrary commands on the web console server — monitor for unexpected PowerShell widget creation or execution originating from SCOM web console processes. ↗
- →Successful exploitation results in SYSTEM-level privilege escalation on the SCOM web console server — alert on SCOM web console server processes spawning child processes with SYSTEM privileges. ↗
- ·Exploitation requires an authenticated SCOM account (any valid login); this is a network-based privilege escalation, not an unauthenticated attack. Detection should focus on authenticated sessions abusing the PowerShell widget feature. ↗
- ·The vulnerability is in the SCOM Web Console component specifically; patches are delivered as WebConsole MSP packages (KB5073251 for one release, KB5071859 and KB5073079 for others). Ensure the web console component is patched, not just the management server. ↗

Microsoft on Tuesday released 84 patches affecting 15 product families – including a few you’ve possibly never encountered. Eight of the addressed issues are considered by Microsoft to be of Critical severity, though none of those affect Windows, nor are they expected to be exploited within the next 30 days. In addition, five of those Critical issues were in fact addressed by Microsoft in advance of Patch Tuesday itself, as we’ll discuss below. Twenty-two have a CVSS base score of 8.0 or higher, including one with a 9.8 base score. None are known to be under active exploit in the wild, but two are publicly disclosed so far.
