Descriptions

The jira.editor.user.mode cookie set by the Jira Editor Plugin in Jira Server and Data Center before version 8.5.12, from version 8.6.0 before version 8.13.4, and from version 8.14.0 before version 8.15.0 allows remote anonymous attackers who can perform an attacker in the middle attack to learn which mode a user is editing in due to the cookie not being set with a secure attribute if Jira was configured to use https.

La cookie jira.editor.user.mode ajustada por Jira Editor Plugin en Jira Server y Data Center versiones anteriores a 8.5.12, desde versión 8.6.0 versiones anteriores a 8.13.4 y desde versión 8.14.0 versiones anteriores a 8.15.0, permite a atacantes anónimos remotos poder llevar a cabo un ataque de tipo attacker in the middle para saber en qué modo está editando un usuario debido a que la cookie no está ajustada con un atributo seguro si Jira estaba configurado para usar https
