The remove_bad_chars function in utils/cups-browsed.c in cups-filters before 1.0.66 allows remote IPP printers to execute arbitrary commands via consecutive shell metacharacters in the (1) model or (2) PDL. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-2707.
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
