The version of IBM WebSphere Application Server running on the remote host is affected by multiple vulnerabilities as referenced in the 7276579 advisory.- IBM WebSphere Application Server and WebSphere Application Server Liberty are vulnerable to HTTP request smuggling. A remote attacker could smuggle a specially crafted request to the application server thereby allowing the attacker to bypass security controls, spoof identity, escalate privilege, and expose sensitive information. CWE: CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') (CVE-2026-8646)
- IBM WebSphere Application Server and WebSphere Application Server Liberty are vulnerable to a denial of service, caused by sending a specially-crafted request. A remote attacker could exploit this vulnerability to cause the server to consume memory resources. CWE: CWE-400: Uncontrolled Resource Consumption (CVE-2026-9071, CVE-2026-9320)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
