CVE-2026-105115: Missing Authentication for Critical Function in OpenIdentityPlatform OpenAM
OpenAM before 16.1.3 contains an unauthenticated arbitrary class instantiation vulnerability in the legacy JAX-RPC SOAP interface that allows remote attackers to load classes without authentication. Attackers can send SOAP requests to /jaxrpc/* with an unverified session identifier and a chosen class name, crashing the server, probing the classpath, or potentially reaching code execution via gadget chains.
AI Analysis
Technical Summary
CVE-2026-105115 describes a missing authentication vulnerability in OpenIdentityPlatform's OpenAM prior to version 16.1.3. The flaw exists in the legacy JAX-RPC SOAP interface, where attackers can send SOAP requests to endpoints under /jaxrpc/* with an unverified session identifier and specify arbitrary class names. This allows remote attackers to instantiate classes without authentication, potentially causing denial of service by crashing the server, probing the classpath, or achieving code execution through gadget chains.
Potential Impact
The vulnerability allows unauthenticated remote attackers to instantiate arbitrary classes via the SOAP interface, which can lead to server crashes, information disclosure through classpath probing, and potentially remote code execution. The CVSS 4.0 score is 8.8 (high severity), indicating significant risk if exploited.
Mitigation Recommendations
A fix is available in OpenAM version 16.1.3. Users should upgrade to version 16.1.3 or later to remediate this vulnerability. No other mitigation guidance is provided in the input data.
