Vulnerability in the Oracle WebLogic Server component of Oracle Fusion Middleware (subcomponent: WLS - Web Services). The supported version that is affected are 10.3.6.0.0, 12.1.3.0.0, 12.2.1.1.0, 12.2.1.2.0 and 12.2.1.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebLogic Server. While the vulnerability is in Oracle WebLogic Server, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle WebLogic Server as well as unauthorized update, insert or delete access to some of Oracle WebLogic Server accessible data and unauthorized read access to a subset of Oracle WebLogic Server accessible data. CVSS 3.0 Base Score 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:H).

url /wls-wsat/CoordinatorPortType↗

path /wls-wsat/CoordinatorPortType↗

• → Monitor for HTTP POST requests targeting the /wls-wsat/CoordinatorPortType endpoint, which is the attack vector for this CVE. ↗
• → Inspect inbound HTTP POST bodies for XML payloads containing sleep/timing-based DoS patterns (e.g., large sleep values) sent to the WLS-WSAT endpoint. ↗
• → Detect outbound DNS lookups from WebLogic server processes to external domains, which may indicate successful exploitation and data exfiltration via DNS. ↗
• → Flag POST requests to /wls-wsat/CoordinatorPortType with Content-Type: text/xml from unauthenticated sources over HTTP/HTTPS. ↗
• → The vulnerability is unauthenticated and network-accessible via HTTP; no credentials are required. Alert on any external access to WLS-WSAT endpoints. ↗

• · Affected versions are specifically 10.3.6.0.0, 12.1.3.0.0, 12.2.1.1.0, 12.2.1.2.0, and 12.2.1.3.0. Detection rules should be scoped to these Oracle WebLogic Server versions. ↗
• · The attack scope is marked as Changed (S:C in CVSS), meaning successful exploitation can impact products beyond the WebLogic server itself — broaden monitoring to adjacent systems. ↗
• · The PoC DNS exfiltration domain is a Burp Collaborator instance used for testing; real-world attackers will substitute their own callback domain. Do not rely on this specific domain as a stable IOC. ↗
