Prior to version 0.17.0, the `confluence_download_attachment` MCP tool accepts a `download_path` parameter that is written to without any directory boundary enforcement. An attacker who can call this tool and supply or access a Confluence attachment with malicious content can write arbitrary content to any path the server process has write access to. Because the attacker controls both the write destination and the written content (via an uploaded Confluence attachment), this constitutes for arbitrary code execution (for example, writing a valid cron entry to `/etc/cron.d/` achieves code execution within one scheduler cycle with no server restart required). Version 0.17.0 fixes the issue."},{"lang":"es","value":"MCP Atlassian es un servidor de Model Context Protocol (MCP) para productos de Atlassian (Confluence y Jira). Antes de la versión 0.17.0, la herramienta MCP 'confluence_download_attachment' acepta un parámetro 'download_path' al que se escribe sin ninguna aplicación de límites de directorio. Un atacante que puede llamar a esta herramienta y proporcionar o acceder a un archivo adjunto de Confluence con contenido malicioso puede escribir contenido arbitrario a cualquier ruta a la que el proceso del servidor tenga acceso de escritura. Debido a que el atacante controla tanto el destino de escritura como el contenido escrito (a través de un archivo adjunto de Confluence subido), esto constituye una ejecución de código arbitrario (por ejemplo, escribir una entrada cron válida en '/etc/cron.d/' logra la ejecución de código dentro de un ciclo del planificador sin necesidad de reiniciar el servidor). La versión 0.17.0 corrige el problema."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","baseScore":9.0,"baseSeverity":"CRITICAL","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.3,"impactScore":6.0},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.0,"baseSeverity":"HIGH","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.1,"impactScore":5.9}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-22"},{"lang":"en","value":"CWE-73"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:mcp-atlassian:mcp_atlassian:*:*:*:*:*:*:*:*","versionEndExcluding":"0.17.0","matchCriteriaId":"972ADC29-1D0B-47D0-8889-A1388AB7F9E7"}]}]}],"references":[{"url":"https://github.com/sooperset/mcp-atlassian/commit/52b9b0997681e87244b20d58034deae89c91631e","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/sooperset/mcp-atlassian/security/advisories/GHSA-xjgw-4wvw-rgm4","source":"security-advisories@github.com","tags":["Vendor Advisory"]}]}}]}
