Summary
In Eclipse Jetty, versions 9.4.27.v20200227 to 9.4.29.v20200521, in case of too large response headers, Jetty throws an exception to produce an HTTP 431 error. When this happens, the ByteBuffer containing the HTTP response headers is released back to the ByteBufferPool twice. Because of this double release, two threads can acquire the same ByteBuffer from the pool and while thread1 is about to use the ByteBuffer to write response1 data, thread2 fills the ByteBuffer with other data. Thread1 then proceeds to write the buffer that now contains different data. This results in client1, which issued request1 seeing data from another request or response which could contain sensitive data belonging to client2 (HTTP session ids, authentication credentials, etc.). If the Jetty version cannot be upgraded, the vulnerability can be significantly reduced by configuring a responseHeaderSize significantly larger than the requestHeaderSize (12KB responseHeaderSize and 8KB requestHeaderSize).

Esto resulta en que el cliente1, que emiti\u00f3 la petici\u00f3n1, ve los datos de otra petici\u00f3n o respuesta que podr\u00eda contener datos sensibles pertenecientes al cliente2 (identificaciones de sesi\u00f3n HTTP, credenciales de autenticaci\u00f3n, etc.). Si no se puede actualizar la versi\u00f3n del muelle, la vulnerabilidad se puede reducir significativamente configurando un responseHeaderSize significativamente mayor que el requestHeaderSize (12KB responseHeaderSize y 8KB requestHeaderSize)\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"LOW\",\"baseScore\":9.4,\"baseSeverity\":\"CRITICAL\"},\"exploitabilityScore\":3.9,\"impactScore\":5.5}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:N/AC:L/Au:N/C:P/I:P/A:P\",\"accessVector\":\"NETWORK\",\"accessComplexity\":\"LOW\",\"authentication\":\"NONE\",\"confidentialityImpact\":\"PARTIAL\",\"integrityImpact\":\"PARTIAL\",\"availabilityImpact\":\"PARTIAL\",\"baseScore\":7.5},\"baseSeverity\":\"HIGH\",\"exploitabilityScore\":10.0,\"impactScore\":6.4,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":false}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-672\"}]},{\"source\":\"emo@eclipse.org\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-672\"},{\"lang\":\"en\",\"value\":\"CWE-675\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:eclipse:jetty:9.4.27:20200227:*:*:*:*:*:*\",\"matchCriteriaId\":\"2E19DD91-3412-493B-AAD2-8171364CF8D0\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:eclipse:jetty:9.4.28:20200408:*:*:*:*:*:*\",\"matchCriteriaId\":\"1AAEAD71-54E4-4001-89A6-93460D277281\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:eclipse:jetty:9.4.29:20200521:*:*:*:*:*:*\",\"matchCriteriaId\":\"C401D149-CEAD-4682-9E4E-83D88D64EF5F\"}]}]}],\"references\":[{\"url\":\"http://www.openwall.com/lists/oss-security/2020/08/17/1\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://bugs.eclipse.org/bugs/show_bug.cgi?id=564984\",\"source\":\"emo@eclipse.org\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://lists.apache.org/thread.html/r29073905dc9139d0d7a146595694bf57bb9e35e5ec6aa73eb9c8443a%40%3Ccommits.pulsar.apache.org%3E\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://lists.apache.org/thread.html/r378e4cdec15e132575aa1dcb6296ffeff2a896745a8991522e266ad4%40%3Ccommits.pulsar.apache.org%3E\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://lists.apache.org/thread.html/r4bdd3f7bb6820a79f9416b6667d718a06d269018619a75ce4b759318%40%3Ccommits.pulsar.apache.org%3E\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://lists.apache.org/thread.html/r521168299e023fb075b57afe33d17ff1d09e8a10e0fd8c775ea0e028%40%3Ccommits.pulsar.apache.org%3E\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://lists.apache.org/thread.html/r7fc5f2ed49641ea91c433e3cd0fc3d31c0278c87b82b15c33b881415%40%3Ccommits.pulsar.apache.org%3E\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://lists.apache.org/thread.html/r81f58591fb4716fb867b36956f30c7c8ad4ab3f23abc952d9d86a2a0%40%3Ccommits.pulsar.apache.org%3E\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://lists.apache.org/thread.html/r9584c4304c888f651d214341a939bd264ed30c9e3d0d30fe85097ecf%40%3Ccommits.pulsar.apache.org%3E\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://lists.apache.org/thread.html/r9a2cfa56d30782a0c17a5deb951a622d1f5c8de48e1c3b578ffc2a84%40%3Ccommits.pulsar.apache.org%3E\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://lists.apache.org/thread.html/ra8661fc8c69c647cb06153c1485d48484a833d873f75dfe45937e9de%40%3Ccommits.pulsar.apache.org%3E\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://lists.apache.org/thread.html/rbe1f230e87ea947593145d0072d0097ddb0af10fee1161db8ca1546c%40%3Ccommits.pulsar.apache.org%3E\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://lists.apache.org/thread.html/rd0e44e8ef71eeaaa3cf3d1b8b41eb25894372e2995ec908ce7624d26%40%3Ccommits.pulsar.apache.org%3E\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://lists.apache.org/thread.html/rd98cfd012490cb02caa1a11aaa0cc38bff2d43bcce9b20c2f01063dd%40%3Ccommits.pulsar.apache.org%3E\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XE6US6VPZHOWFMUSFGDS5V2DNQPY5MKB/\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://www.oracle.com/security-alerts/cpuApr2021.html\",\"source\":\"emo@eclipse.org\"},{\"url\":\"https://www.oracle.com/security-alerts/cpuoct2020.html\",\"source\":\"emo@eclipse.org\"}]}}"
