Title: H-Sphere Webshell Command2.CC Zipfile URI Parameter Command Execution Vulnerability
Severity: HIGH
Description:
H-Sphere is a multiserver web hosting application. H-Sphere ships with WebShell, a component designed to be a file manager for uploading downloading files via FTP. H-Sphere is available for the Windows, Linux, and Unix operating systems.
The H-Sphere Webshell component is prone to a remote command execution vulnerability.
This issue exists in the 'command2.CC' source file and is due to insufficient validation of input supplied via the 'zipfile' URI parameter. It is possible for a remote attacker to supply shell commands via this URI parameter, which will be executed with the privileges of Webshell.
Exploitation of this vulnerability will allow the attacker to gain interactive and possibly privileged access to the underlying host.
It should be noted that this issue was discovered in H-Sphere 2.3 RC3. It is not yet known whether earlier versions are also vulnerable.
Affected Products:
- Positive Software H-Sphere 2.3.0 RC3
