CVE-2022-41915 (GCVE-0-2022-41915)

Vulnerability from cvelistv5 – Published: 2022-12-13 00:00 – Updated: 2025-04-22 15:57
VLAI?
Summary
Netty project is an event-driven asynchronous network application framework. Starting in version 4.1.83.Final and prior to 4.1.86.Final, when calling `DefaultHttpHeadesr.set` with an _iterator_ of values, header value validation was not performed, allowing malicious header values in the iterator to perform HTTP Response Splitting. This issue has been patched in version 4.1.86.Final. Integrators can work around the issue by changing the `DefaultHttpHeaders.set(CharSequence, Iterator<?>)` call, into a `remove()` call, and call `add()` in a loop over the iterator of values.
Severity ?

A partir de la versi\u00f3n 4.1.83.Final y anteriores a la 4.1.86.Final, al llamar a `DefaultHttpHeadesr.set` con un _iterator_ de valores, no se realizaba la validaci\u00f3n del valor del encabezado, lo que permit\u00eda que los valores de encabezado maliciosos en el iterador realizaran la divisi\u00f3n de respuesta HTTP. Este problema se solucion\u00f3 en la versi\u00f3n 4.1.86.Final. Los integradores pueden solucionar el problema cambiando la llamada `DefaultHttpHeaders.set(CharSequence, Iterator)` a una llamada `remove()` y llamando a `add()` en un bucle sobre el iterador de valores.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N\",\"baseScore\":6.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"LOW\",\"integrityImpact\":\"LOW\",\"availabilityImpact\":\"NONE\"},\"exploitabilityScore\":3.9,\"impactScore\":2.5},{\"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:L/I:L/A:N\",\"baseScore\":6.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"LOW\",\"integrityImpact\":\"LOW\",\"availabilityImpact\":\"NONE\"},\"exploitabilityScore\":3.9,\"impactScore\":2.5}]},\"weaknesses\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-113\"},{\"lang\":\"en\",\"value\":\"CWE-436\"}]},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-436\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:netty:netty:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.1.83\",\"versionEndExcluding\":\"4.1.86\",\"matchCriteriaId\":\"B032F19E-5D82-4C06-8D4B-AE3810E893B7\"}]}]},{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"07B237A9-69A3-4A9C-9DA0-4E06BD37AE73\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:debian:debian_linux:11.0:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"FA6FEEC2-9F11-4643-8827-749718254FED\"}]}]}],\"references\":[{\"url\":\"https://github.com/netty/netty/commit/fe18adff1c2b333acb135ab779a3b9ba3295a1c4\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Patch\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/netty/netty/issues/13084\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Exploit\",\"Issue Tracking\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/netty/netty/pull/12760\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Patch\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/netty/netty/security/advisories/GHSA-hh82-3pmq-7frp\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Mitigation\",\"Third Party Advisory\"]},{\"url\":\"https://lists.debian.org/debian-lts-announce/2023/01/msg00008.html\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Mailing List\",\"Third Party Advisory\"]},{\"url\":\"https://security.netapp.com/advisory/ntap-20230113-0004/\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://www.debian.org/security/2023/dsa-5316\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://github.com/netty/netty/commit/fe18adff1c2b333acb135ab779a3b9ba3295a1c4\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/netty/netty/issues/13084\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Exploit\",\"Issue Tracking\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/netty/netty/pull/12760\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/netty/netty/security/advisories/GHSA-hh82-3pmq-7frp\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Mitigation\",\"Third Party Advisory\"]},{\"url\":\"https://lists.debian.org/debian-lts-announce/2023/01/msg00008.html\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Mailing List\",\"Third Party Advisory\"]},{\"url\":\"https://security.netapp.com/advisory/ntap-20230113-0004/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://www.debian.org/security/2023/dsa-5316\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\"]}]}}"
