CVE-2020-6798 (GCVE-0-2020-6798)

Vulnerability from cvelistv5 – Published: 2020-03-02 04:05 – Updated: 2024-08-04 09:11
VLAI
Summary
If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer a cross-site scripting vulnerability as a result. In general, this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but is potentially a risk in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5.
Severity
No CVSS data available.
CWE
  • Incorrect parsing of template tag could result in JavaScript injection

Un sitio que se bas\u00f3 en que el navegador se comportara correctamente podr\u00eda sufrir una vulnerabilidad de tipo cross-site scripting como resultado de ello. En general, este fallo no puede ser explotado por medio del correo electr\u00f3nico en el producto Thunderbird porque el scripting es deshabilitado cuando se lee el correo, pero es potencialmente un riesgo en el navegador o en contextos similares a los del navegador. Esta vulnerabilidad afecta a Thunderbird versiones anteriores a 68.5, Firefox versiones anteriores a 73, y Firefox versiones anteriores a ESR68.5.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N\",\"baseScore\":6.1,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"REQUIRED\",\"scope\":\"CHANGED\",\"confidentialityImpact\":\"LOW\",\"integrityImpact\":\"LOW\",\"availabilityImpact\":\"NONE\"},\"exploitabilityScore\":2.8,\"impactScore\":2.7}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:N/AC:M/Au:N/C:N/I:P/A:N\",\"baseScore\":4.3,\"accessVector\":\"NETWORK\",\"accessComplexity\":\"MEDIUM\",\"authentication\":\"NONE\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"PARTIAL\",\"availabilityImpact\":\"NONE\"},\"baseSeverity\":\"MEDIUM\",\"exploitabilityScore\":8.6,\"impactScore\":2.9,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":true}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-79\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:mozilla:firefox:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"73.0\",\"matchCriteriaId\":\"D881BDA7-3601-4A45-991F-4B2B187A73D0\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:mozilla:firefox_esr:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"68.5.0\",\"matchCriteriaId\":\"17B5BB4D-FF9F-433C-A3AC-E4F34C3D75D9\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:mozilla:thunderbird:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"68.5.0\",\"matchCriteriaId\":\"BED2E060-4B8C-403F-B1E9-D45E2511D1CA\"}]}]}],\"references\":[{\"url\":\"https://bugzilla.mozilla.org/show_bug.cgi?id=1602944\",\"source\":\"security@mozilla.org\",\"tags\":[\"Permissions Required\"]},{\"url\":\"https://security.gentoo.org/glsa/202003-02\",\"source\":\"security@mozilla.org\"},{\"url\":\"https://security.gentoo.org/glsa/202003-10\",\"source\":\"security@mozilla.org\"},{\"url\":\"https://usn.ubuntu.com/4278-2/\",\"source\":\"security@mozilla.org\"},{\"url\":\"https://usn.ubuntu.com/4328-1/\",\"source\":\"security@mozilla.org\"},{\"url\":\"https://usn.ubuntu.com/4335-1/\",\"source\":\"security@mozilla.org\"},{\"url\":\"https://www.mozilla.org/security/advisories/mfsa2020-05/\",\"source\":\"security@mozilla.org\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://www.mozilla.org/security/advisories/mfsa2020-06/\",\"source\":\"security@mozilla.org\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://www.mozilla.org/security/advisories/mfsa2020-07/\",\"source\":\"security@mozilla.org\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://bugzilla.mozilla.org/show_bug.cgi?id=1602944\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Permissions Required\"]},{\"url\":\"https://security.gentoo.org/glsa/202003-02\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://security.gentoo.org/glsa/202003-10\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://usn.ubuntu.com/4278-2/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://usn.ubuntu.com/4328-1/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://usn.ubuntu.com/4335-1/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://www.mozilla.org/security/advisories/mfsa2020-05/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://www.mozilla.org/security/advisories/mfsa2020-06/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://www.mozilla.org/security/advisories/mfsa2020-07/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Vendor Advisory\"]}]}}"
