Descriptions
The ReplaceText extension through 1.41 for MediaWiki has Incorrect Access Control. When a user is blocked after submitting a replace job, the job is still run, even if it may be run at a later time (due to the job queue backlog)
La extensión ReplaceText hasta la 1.41 para MediaWiki presenta un Control de Acceso Incorrecto. Cuando un usuario está bloqueado después de enviar un trabajo de reemplazo, el trabajo se sigue ejecutando, incluso si es posible ejecutar en un momento posterior (debido a una cola de espera de trabajos)
Multiple security issues were found in MediaWiki, a website engine for collaborative work, which could result in cross-site scripting, denial of service and a bypass of restrictions in the "Replace Text" extension.
