highlight.php in (1) RUNCMS 1.1A, (2) CIAMOS 0.9.2 RC1, (3) e-Xoops 1.05 Rev3, and possibly other products based on e-Xoops (exoops), allows remote attackers to read arbitrary PHP files by specifying the pathname in the file parameter, as demonstrated by reading database configuration information from mainfile.php.

RUNCMS 1.1A, and possibly other products based on e-Xoops (exoops), when "Allow custom avatar upload" is enabled, does not properly verify uploaded files, which allows remote attackers to upload arbitrary files.
