Title: CGI_lite.pm Insecure Input Handling Vulnerability
Severity: MODERATE
Description:
It is possible for users to access sensitive files remotely due to a problem in the CGI_lite.pm module. The CGI_lite.pm module allows users to upload files to a remote system. However, due to inadequate checking of the input of filenames by the module, it is possible to either view the contents of a file, or arbitrarily execute a command on a host using the module. The $filename variable within the modules does not adequately escape the inputted data when creating a file. Therefore, when a command is entered through a form POST method, it is piped directly to a shell. Therefore, a user with malicious intentions could use this to either view the contents of files readable by the UID of the httpd process, or execute commands with the inherited UID and GID of the httpd process.

- Shishir Gundavaram CGI_lite.pm 1.62.0
