CVSS: 4.3EPSS: 0%CPEs: 5EXPL: 0CVE-2021-23968 – Mozilla: Content Security Policy violation report could have contained the destination of a redirect
https://notcve.org/view.php?id=CVE-2021-23968
If Content Security Policy blocked frame navigation, the full destination of a redirect served in the frame was reported in the violation report; as opposed to the original frame URI. This could be used to leak sensitive information contained in such URIs. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8. Si la Política de Seguridad de Contenido bloqueaba la navegación de tramas, el destino completo de un redireccionamiento servido en la trama se reportaba en el informe de infracción; a diferencia del URI de la trama original. Esto podría ser usado para filtrar información confidencial contenida en dichos URI. • https://bugzilla.mozilla.org/show_bug.cgi?id=1687342 https://lists.debian.org/debian-lts-announce/2021/03/msg00000.html https://security.gentoo.org/glsa/202104-09 https://security.gentoo.org/glsa/202104-10 https://www.debian.org/security/2021/dsa-4866 https://www.mozilla.org/security/advisories/mfsa2021-07 https://www.mozilla.org/security/advisories/mfsa2021-08 https://www.mozilla.org/security/advisories/mfsa2021-09 https://access.redhat.com/security/cve/CVE-2021-23968 https:&# • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-209: Generation of Error Message Containing Sensitive Information •
CVSS: 4.3EPSS: 0%CPEs: 5EXPL: 0CVE-2021-23969 – Mozilla: Content Security Policy violation report could have contained the destination of a redirect
https://notcve.org/view.php?id=CVE-2021-23969
As specified in the W3C Content Security Policy draft, when creating a violation report, "User agents need to ensure that the source file is the URL requested by the page, pre-redirects. If that’s not possible, user agents need to strip the URL down to an origin to avoid unintentional leakage." Under certain types of redirects, Firefox incorrectly set the source file to be the destination of the redirects. This was fixed to be the redirect destination's origin. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8. • https://bugzilla.mozilla.org/show_bug.cgi?id=1542194 https://lists.debian.org/debian-lts-announce/2021/03/msg00000.html https://security.gentoo.org/glsa/202104-09 https://security.gentoo.org/glsa/202104-10 https://www.debian.org/security/2021/dsa-4866 https://www.mozilla.org/security/advisories/mfsa2021-07 https://www.mozilla.org/security/advisories/mfsa2021-08 https://www.mozilla.org/security/advisories/mfsa2021-09 https://access.redhat.com/security/cve/CVE-2021-23969 https:&# • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
