To perform this attack, an attacker must have write access to the index file (which can occur during a MITM attack on a non-SSL connection). This issue has been patched in Helm 3.3.2 and 2.16.11. A possible workaround is to manually review the index file in the Helm repository cache before installing software."}, {"lang": "es", "value": "En Helm versiones anteriores a 2.16.11 y 3.3.2, un repositorio de Helm puede contener duplicados del mismo gr\u00e1fico, y siempre se usa el \u00faltimo. Si un repositorio est\u00e1 comprometido, esto reduce el nivel de acceso que necesita un atacante para inyectar un gr\u00e1fico incorrecto en un repositorio. Para llevar a cabo este ataque, un atacante necesita tener acceso de escritura al archivo de index (lo que puede ocurrir durante un ataque MITM en una conexi\u00f3n no SSL). Este problema ha sido corregido en Helm versiones 3.3.2 y 2.16.11. Una posible soluci\u00f3n es revisar manualmente el archivo index en la cach\u00e9 del repositorio de Helm antes de instalar el software"}], "lastModified": "2024-11-21T05:05:01.830", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:helm:helm:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "455BCCE5-1D43-4E59-9591-E84B52DAAF0B", "versionEndExcluding": "2.16.11", "versionStartIncluding": "2.0.0"}, {"criteria": "cpe:2.3:a:helm:helm:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B462D769-3FC0-4079-8B48-863F013662EF", "versionEndExcluding": "3.3.2", "versionStartIncluding": "3.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
