Tower runs a memcached, which is accessed via TCP. An attacker can take advantage of writing a playbook polluting this cache, causing a denial of service attack. This attack would not completely stop the service, but in the worst-case scenario, it can reduce the Tower performance, for which memcached is designed. Theoretically, more sophisticated attacks can be performed by manipulating and crafting the cache, as Tower relies on memcached as a place to pull out setting values. Confidential and sensitive data stored in memcached should not be pulled, as this information is encrypted. This flaw affects Ansible Tower versions before 3.6.4, Ansible Tower versions before 3.5.6 and Ansible Tower versions before 3.4.6."},{"lang":"es","value":"Se encontró un fallo en Ansible Tower cuando se ejecuta Openshift. Tower ejecuta un memcached, al que es accedido por medio de TCP. Un atacante puede explotar la posibilidad de escribir un libro de jugadas que contamine este caché y causar un ataque de denegación de servicio. Este ataque no detendría por completo el servicio, pero en el peor de los casos, puede reducir el rendimiento de la torre, para lo cual está diseñado Memcached. En teoría, más ataques sofisticados pueden ser llevados a cabo al manipular y diseñar la caché, ya que Tower confía en memcached como un lugar para extraer valores de configuración. Los datos confidenciales y sensibles almacenados en memcached no deben ser extraidos, ya que esta información está cifrada. Este fallo afecta a Ansible Tower versiones anteriores a 3.6.4, Ansible Tower versiones anteriores a 3.5.6 y  Ansible Tower a  versiones anteriores a 3.4.6"}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L","baseScore":4.4,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":1.8,"impactScore":2.5}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:L/AC:L/Au:N/C:P/I:N/A:P","baseScore":3.6,"accessVector":"LOCAL","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"PARTIAL","integrityImpact":"NONE","availabilityImpact":"PARTIAL"},"baseSeverity":"LOW","exploitabilityScore":3.9,"impactScore":4.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"secalert@redhat.com","type":"Secondary","description":[{"lang":"en","value":"CWE-862"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-Other"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:redhat:ansible_tower:*:*:*:*:*:*:*:*","versionEndExcluding":"3.4.6","matchCriteriaId":"50566FBA-06F5-461A-A9A5-87E9FC98B085"},{"vulnerable":true,"criteria":"cpe:2.3:a:redhat:ansible_tower:*:*:*:*:*:*:*:*","versionStartIncluding":"3.5.0","versionEndExcluding":"3.5.6","matchCriteriaId":"90C46E3E-82AF-4E9F-AB9A-856988169454"},{"vulnerable":true,"criteria":"cpe:2.3:a:redhat:ansible_tower:*:*:*:*:*:*:*:*","versionStartIncluding":"3.6.0","versionEndExcluding":"3.6.4","matchCriteriaId":"F1299B71-D05C-4871-ABC0-F70AA3730FFB"}]}]}],"references":[{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=1818445","source":"secalert@redhat.com","tags":["Issue Tracking","Vendor Advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=1818445","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Issue Tracking","Vendor Advisory"]}]}}]}
