A critical unauthenticated command injection vulnerability located inside an enterprise IT orchestration bridge component has been resolved, preventing external threat networks from pivoting directly into internal subnets. The defect enables unauthenticated remote actors to transmit malformed SOAP parameters to execute arbitrary shell scripts on hosting servers.
The vulnerability, tracked as CVE-2026-38910 and carrying a CVSS score of 9.8, impacts ServiceNow MID Server installations associated with Washington DC, Xanadu, and Yokohama release tracks. The underlying error stems from insufficient input sanitization within SOAP message parsing subroutines. Because MID Servers are deployed inside internal corporate networks to execute automated commands and fetch data for cloud instances, an attacker exploiting this endpoint can execute arbitrary operating system commands with local system privileges.
Compromising an enterprise MID Server represents a severe breach of internal network boundaries. Because MID Server instances hold cached administrative credentials and maintain direct connections to internal Active Directory, database, and virtualization assets, an unauthorized host takeover permits threat actors to steal internal domain hashes, bypass perimeter firewall filters, and launch horizontal movement loops.
– Apply emergency security patches and cumulative hotfixes distributed by ServiceNow across all active MID Server instances immediately.
– Restrict inbound network connectivity to MID Server SOAP endpoints, allowing communications exclusively from verified ServiceNow cloud IP ranges.
– Audit local MID Server host execution logs for anomalous process creations or unexpected PowerShell invocations.
– Ensure host service profiles operating MID Server daemons run under least-privilege service account configurations rather than local system accounts.
IT orchestration safety relies on strict input parameter sanitization combined with rigid network access controls to guarantee that internal gateway connectors cannot serve as unmonitored entry pathways into corporate subnets. #CodeDefence #ServiceNow #MIDServer #RCE #CommandInjection #AppSec #CloudSecurity
