          "value": "0day Rubbish Research Team is publicly disclosing a vulnerability in\nLightstreamer Server 7.4.8 build 3506 (with JMS Extender 2.1.0).\n\nType: unauthenticated JMX inspection console allowing an anonymous caller to\ninvoke any MBean operation, reaching jvmtiAgentLoad on\ncom.sun.management:type=DiagnosticCommand to load and run a native agent\nlibrary inside the broker JVM (CWE-306, CWE-345, CWE-20, CWE-250, CWE-1188)\n\nScoring. This finding is dual-scored on one documented delivery precondition,\nand both figures are published rather than a single headline number:\n- PRIMARY, 8.1 High, CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H. This is the\n  conservative figure for an attacker with network access only: the agent\n  library must be delivered to a filesystem path by means outside this endpoint.\n- CONDITIONAL, 9.8 Critical, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. This\n  is the shipped-default exposure where the precondition is ALREADY satisfied,\n  that is a native shared object is already reachable at a filesystem path the\n  attacker names. Exploitation is then one deterministic HTTP request. The 9.8\n  figure is conditional, not the primary rating, and is not the headline.\n\nImpact: native code execution inside the Lightstreamer JVM as the service\nprocess, inheriting that process\u0027s full identity. In the verified deployment the\nprocess ran as uid=0(root), so the executed commands ran as root; root is not\nclaimed to be a factory-mandated identity, it is whatever account launched the\nservice. The shipping configuration sets \u003cjmxtree_enabled\u003eY\u003c/jmxtree_enabled\u003e\nand \u003cdashboard\u003e\u003cpublic\u003eY\u003c/public\u003e even though the adjacent comments claim the\ndefault is N, and the only remaining check is a Referer header matching the\ntarget host, which any HTTP client forges.\n\nAuthentication: unauthenticated (no credential of any kind).\n\nVerification boundary, stated plainly. We verified the MBean-invocation and\nnative-code-execution legs against a research-host deployment reached over\nloopback (HTTP 200 with \"return code: 0\", marker files recording uid=0(root),\nand id/whoami commands chosen by the HTTP client at send time). The native\nagent library, however, was already present on disk, placed beforehand over an\nauthenticated root session. jvmtiAgentLoad takes a filesystem path and fetches\nnothing (http:// and file:// were both treated as literal strings), so the\nfully remote chain including payload delivery is NOT demonstrated by this\nadvisory; what is proven unauthenticated is the request leg, not the delivery\nleg.\n\nFull technical analysis and a reproducible proof-of-concept:\n  https://0day-rubbish.com/blog/lightstreamer-unauth-jmx-jvmti-agentload-rce\n\nProject archive (ongoing disclosure series):\n  https://github.com/Exploit-Garbage/0day-Rubbish\n\nThe vendor has been notified through its published security contact. No vulnerability identifier has been assigned to\nthis finding yet.\n\n--\n0day Rubbish Research Team\ndisclosure () 0day-rubbish com\nhttps://0day-rubbish.com\n_______________________________________________\nSent through the Full Disclosure mailing list\nhttps://nmap.org/mailman/listinfo/fulldisclosure\nWeb Archives \u0026 RSS: https://seclists.org/fulldisclosure/"
