CVE-2022-22947

CVE-2022-22947 is a code injection (Spring Expression Language injection) flaw in VMware Spring Cloud Gateway that allows arbitrary remote code execution when the Gateway Actuator endpoint is enabled, exposed, and unsecured. A remote, unauthenticated attacker can send a maliciously crafted request (typically a crafted POST to the gateway actuator routes endpoint) that is evaluated as code, letting the attacker run arbitrary commands on the host. The CVSS 3.1 score is 10.0 (critical) because exploitation is network-based, requires no privileges or user interaction, and impacts confidentiality, integrity, and availability beyond the vulnerable component. All Spring Cloud Gateway deployments prior to 3.1.1/3.0.7 are affected, along with Oracle products that embed the component, including Commerce Guided Search and multiple Oracle Communications Cloud Native Core functions. Exploitation is confirmed: the flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2022-05-16, EPSS puts the 30-day exploitation probability at 98.3% (100th percentile), public PoC exploits exist, and related reporting describes botnets adding Spring Cloud Gateway exploits to their attack tooling.

What to do: Upgrade Spring Cloud Gateway to 3.1.1 or later, or to 3.0.7 or later on the 3.0.x line, per VMware's advisory, and apply the relevant Oracle Critical Patch Update for affected Oracle Commerce Guided Search and Communications Cloud Native Core products. If you cannot patch immediately, disable or restrict the Gateway Actuator endpoint so it is not reachable over the network without authentication. Scan for exposed gateway actuator endpoints and review hosts for signs of command execution; this flaw is on CISA's KEV list, which requires applying updates per vendor instructions.
