CVE-2024-8660

Status: AnalyzedMedium (4.6)—

Concrete CMS versions 9.0.0 through 9.3.3 are affected by a stored XSS vulnerability in the "Top Navigator Bar" block. Since the "Top Navigator Bar" output was not sufficiently sanitized, a rogue administrator could add a malicious payload that could be executed when targeted users visited the home page.The Concrete CMS Security Team gave this vulnerability a CVSS v4 score of 4.6 with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N . This does not affect versions below 9.0.0 since they do not have the Top Navigator Bar Block. Thanks, Chu Quoc Khanh for reporting.

Dado que la salida de la \"Barra de navegación superior\" no se desinfectó lo suficiente, un administrador malintencionado podría agregar una carga maliciosa que podría ejecutarse cuando los usuarios objetivo visitaran la página de inicio. El equipo de seguridad de Concrete CMS le dio a esta vulnerabilidad una puntuación CVSS v4 de 4,6 con el vector CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N . Esto no afecta a las versiones anteriores a la 9.0.0, ya que no tienen el bloque de la barra de navegación superior. Gracias, Chu Quoc Khanh, por informarnos."
