GuppY dwnld.php file deletion
| guppy-dwnld-file-deletion (25141) |  Medium Risk |
Description:
GuppY could allow a remote attacker to delete arbitrary files. If magic_quotes_gpc is disabled, a remote attacker could send a specially-crafted URL request to the dwnld.php script directory containing "%2E dot" sequences (%2E./), which would allow the attacker to view arbitrary files located on the vulnerable system with privileges of the Web server process. It is also possible to append a NULL byte character (%00) to the targeted file name and delete or corrupt known files that are chmod 666.
Platforms Affected:
- FreeGuppy, GuppY 4.5.11 and prior
Remedy:
Upgrade to the latest version of GuppY (4.5.12 or later), available from the GuppY Web site. See References.
Consequences:
