Severity ?
5.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N
Summary
SummaryThis advisory addresses an Open Redirection vulnerability in Mautic's user unlocking endpoint. This vulnerability could be exploited by an attacker to redirect legitimate users to malicious websites, potentially leading to phishing attacks or the delivery of exploit kits. Open Redirection via returnUrl Parameter: An Open Redirection vulnerability exists in the /s/action/unlock/user.user/0 endpoint. The returnUrl parameter, intended for post-action redirection, is not properly validated. This allows an attacker to craft a URL that, when clicked by a user, redirects them to an arbitrary external website controlled by the attacker. MitigationUpdate Mautic to a version that properly validates or sanitizes the returnUrl parameter to ensure that redirects only occur to trusted, internal URLs or explicitly whitelisted domains.

Un atacante podr\u00eda aprovechar esta vulnerabilidad para redirigir a usuarios leg\u00edtimos a sitios web maliciosos, lo que podr\u00eda provocar ataques de phishing o la entrega de kits de explotaci\u00f3n. Redirecci\u00f3n abierta mediante el par\u00e1metro returnUrl: Existe una vulnerabilidad de redirecci\u00f3n abierta en el endpoint /s/action/unlock/user.user/0. El par\u00e1metro returnUrl, destinado a la redirecci\u00f3n posterior a la acci\u00f3n, no est\u00e1 validado correctamente. Esto permite a un atacante manipular una URL que, al hacer clic en ella, redirige a un sitio web externo arbitrario controlado por el atacante. Mitigaci\u00f3n: Actualice Mautic a una versi\u00f3n que valide o depure correctamente el par\u00e1metro returnUrl para garantizar que las redirecciones solo se realicen a URL internas de confianza o a dominios expl\u00edcitamente incluidos en la lista blanca."
