Redmine en versiones anteriores a la 3.2.9, 3.3.x anteriores a 3.3.6 y 3.4.x anteriores a 3.4.4 no bloquea los flags --config y --debugger en el programa Mercurial hg, lo que permite que los atacantes remotos ejecuten comandos arbitrarios (mediante el adaptador Mercurial) por medio de vectores que involucran una rama cuyo nombre empieza con una subcadena --config= o --debugger=. Esta vulnerabilidad está relacionada con CVE-2017-17536.
