The #sinclude directive in Embedded Perl (ePerl) 2.2.14 and earlier allows a remote attacker to execute arbitrary code by modifying the 'sinclude' file to point to another file that contains a #include directive that references a file that contains the code.
ePerl 2.2.12 allows remote attackers to read arbitrary files and possibly execute certain commands by specifying a full pathname of the target file as an argument to bar.phtml.
