The vulnerability arises from the application's failure to properly sanitize and validate user-supplied URLs before embedding them into the application UI as external links with custom icons. Specifically, the application does not prevent the inclusion of 'javascript:' protocol payloads in URLs, which can be exploited by a user with manager role to execute arbitrary JavaScript code in the context of another user's session. This flaw can be leveraged to steal the admin's authorization token by crafting malicious URLs that, when clicked by the admin, send the token to an attacker-controlled server. The attacker can then use this token to perform unauthorized actions, escalate privileges to admin, or directly take over the admin account. The vulnerability is triggered when the malicious link is opened in a new tab using either the CTRL + left mouse button click or the mouse scroll wheel click, or in some non-updated versions of modern browsers, by directly clicking on the link."}, {"lang": "es", "value": "Existe una vulnerabilidad de Cross-site Scripting (XSS) almacenado en la aplicaci\u00f3n mintplex-labs/anything-llm, que afecta a las versiones hasta la \u00faltima anterior a la 1.0.0 incluida. La vulnerabilidad surge de la falla de la aplicaci\u00f3n al sanitizar y validar adecuadamente las URL proporcionadas por el usuario antes de incrustarlas en la interfaz de usuario de la aplicaci\u00f3n como enlaces externos con \u00edconos personalizados. Espec\u00edficamente, la aplicaci\u00f3n no impide la inclusi\u00f3n de payloads del protocolo 'javascript:' en las URL, que pueden ser explotadas por un usuario con rol de administrador para ejecutar c\u00f3digo JavaScript arbitrario en el contexto de la sesi\u00f3n de otro usuario. Esta falla se puede aprovechar para robar el token de autorizaci\u00f3n del administrador mediante la creaci\u00f3n de URL maliciosas que, cuando el administrador hace clic en ellas, env\u00edan el token a un servidor controlado por el atacante. Luego, el atacante puede usar este token para realizar acciones no autorizadas, escalar privilegios al administrador o tomar directamente el control de la cuenta de administrador. La vulnerabilidad se activa cuando el enlace malicioso se abre en una nueva pesta\u00f1a usando CTRL + clic con el bot\u00f3n izquierdo del mouse o clic con la rueda de desplazamiento del mouse, o en algunas versiones no actualizadas de los navegadores modernos, al hacer clic directamente en el enlace."}], "lastModified": "2024-10-15T20:01:31.567", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:mintplexlabs:anythingllm:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "0D667E32-5A5C-479C-BB81-47F3BCA38C13", "versionEndExcluding": "1.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security@huntr.dev"}
