Title: GuppY Error.PHP Remote File Include and Command Execution Vulnerability
Severity: HIGH
Description:
GuppY is portal software implemented in PHP.
GuppY is prone to a remote file-include vulnerability because it fails to properly sanitize user-supplied input.
Specificially, the 'REMOTE_ADDR' variable of the 'error.php' script isn't properly sanitized, allowing attackers to specify remotely hosted script files to be executed in the context of the webserver hosting the vulnerable software.
An attacker can exploit this issue to execute arbitrary remote PHP code on an affected computer with the privileges of the webserver process. This may facilitate unauthorized access.
An attacker can also pass malicious PHP commands through this script to be executed on an affected server, which could facilitate unauthorized access as well.
GuppY 4.5.16 and prior versions are vulnerable.
Affected Products:
- Guppy GuppY 4.5.0
- Guppy GuppY 4.5.16
- Guppy GuppY 4.5.3
- Guppy GuppY 4.5.3 a
- Guppy GuppY 4.5.4
- Guppy GuppY 4.5.9
