CVE-2011-0063

The _list_file_get function in lib/Majordomo.pm in Majordomo 2 20110203 and earlier allows remote attackers to conduct directory traversal attacks and read arbitrary files via a ./.../ sequence in the "extra" parameter to the help command, which causes the regular expression to produce .. (dot dot) sequences. NOTE: this vulnerability is due to an incomplete fix for CVE-2011-0049.

La función _list_file_get de lib/Majordomo.pm de Majordomo 2 20110203 y anteriores permite a atacantes remotos realizar un ataque de salto de directorio y leer archivos arbitrarios a través de la secuencia ./.../ en el parámetro "extra" del comando help, lo que provoca que la expresión regular produzca secuencias .. (punto punto). NOTA: esta vulnerabilidad se debe a un solución incompleta al CVE-2011-0049.
