23846
GuppY dwnld.php pg Variable Arbitrary File Overwrite
Remote / Network Access Input Manipulation
Loss of Availability
Exploit Public

- 漏洞描述

Guppy contains a flaw that may allow a remote denial of service. The issue is caused by the improper sanitization of the 'pg' variable in dwnld.php before being used to write a counter value to '.dtb' files. An attacker can overwrite any file with permissions set to 666 via null injection resulting in a loss of availability for the service.
