Severity ?
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Summary
qutebrowser is an open source keyboard-focused browser with a minimal GUI. Starting with qutebrowser v1.7.0, the Windows installer for qutebrowser registers a `qutebrowserurl:` URL handler. With certain applications, opening a specially crafted `qutebrowserurl:...` URL can lead to execution of qutebrowser commands, which in turn allows arbitrary code execution via commands such as `:spawn` or `:debug-pyeval`. Only Windows installs where qutebrowser is registered as URL handler are affected. The issue has been fixed in qutebrowser v2.4.0. The fix also adds additional hardening for potential similar issues on Linux (by adding the new --untrusted-args flag to the .desktop file), though no such vulnerabilities are known.

Con determinadas aplicaciones, la apertura de una URL \\\"qutebrowserurl:...\\\" especialmente diseñada puede conllevar a una ejecución de comandos de qutebrowser, lo que a su vez permite una ejecución de código arbitrario por medio de comandos como \\\":spawn\\\" o \\\":debug-pyeval\\\". Sólo están afectadas las instalaciones de Windows en las que qutebrowser está registrado como manejador de URL. El problema ha sido corregido en qutebrowser versión v2.4.0. La corrección también añade un refuerzo adicional para posibles problemas similares en Linux (al añadir la nueva flag --untrusted-args al archivo .desktop), aunque no se conoce ninguna vulnerabilidad de este tipo\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H\",\"baseScore\":8.8,\"baseSeverity\":\"HIGH\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"REQUIRED\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":2.8,\"impactScore\":5.9}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:N/AC:M/Au:N/C:P/I:P/A:P\",\"baseScore\":6.8,\"accessVector\":\"NETWORK\",\"accessComplexity\":\"MEDIUM\",\"authentication\":\"NONE\",\"confidentialityImpact\":\"PARTIAL\",\"integrityImpact\":\"PARTIAL\",\"availabilityImpact\":\"PARTIAL\"},\"baseSeverity\":\"MEDIUM\",\"exploitabilityScore\":8.6,\"impactScore\":6.4,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":true}]},\"weaknesses\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-77\"},{\"lang\":\"en\",\"value\":\"CWE-88\"},{\"lang\":\"en\",\"value\":\"CWE-641\"}]},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-77\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:qutebrowser:qutebrowser:*:*:*:*:*:*:*:*\",\"versionEndIncluding\":\"1.7.0\",\"matchCriteriaId\":\"3A51F2F8-D1B6-4749-87C5-6745A246B3FE\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:qutebrowser:qutebrowser:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"2.0.0\",\"versionEndExcluding\":\"2.4.0\",\"matchCriteriaId\":\"F643B197-DBB9-48A2-AD9B-CF2639EDD35A\"}]}]}],\"references\":[{\"url\":\"https://github.com/qutebrowser/qutebrowser/commit/8f46ba3f6dc7b18375f7aa63c48a1fe461190430\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Patch\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/qutebrowser/qutebrowser/security/advisories/GHSA-vw27-fwjf-5qxm\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://github.com/qutebrowser/qutebrowser/commit/8f46ba3f6dc7b18375f7aa63c48a1fe461190430\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/qutebrowser/qutebrowser/security/advisories/GHSA-vw27-fwjf-5qxm\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\"]}]}}",
