PerlDesk pdesk.cgi script directory traversal
| perldesk-directory-traversal (19712) |  Medium Risk |
Description:
PerlDesk could allow a remote attacker to traverse directories on the Web server, caused by improper validation of user-supplied input in the pdesk.cgi script. A remote authenticated attacker using the lang variable could send a specially-crafted request containing "dot dot" sequences (/../) to traverse directories and view arbitrary files outside the Web root directory.
