Title: ePerl Foreign Code Execution Vulnerability
Severity: HIGH
Description:
ePerl is a multipurpose Perl filter and interpreter program for Unix systems.
ePerl provides a preprocessor that allows additional files to be loaded and processed at runtime, through the use of the 'include' directive. A secure variant of the 'include' directive, 'sinclude,' is provided so external data can be loaded and not processed. The user-supplied file path given with these directives can be a relative or absolute path for the local filesystem, or a fully qualified HTTP URL.
An input validation error exists in this preprocessor. If a file referenced by a 'sinclude' directive contains an 'include' directive, the contents of the file referred to by that directive will be loaded and executed.
In a situation where the 'sinclude' directive references a file outside of the script owner's control, it may be possible for the owner of the file to cause arbitrary code/commands to be executed the next time the script is run.
