Title: ZBSoft ZBServer Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
ZBSoft ZBServer Pro is an Internet and Intranet server that supports HTTP, Gopher, FTP and Chat Services. ZBServer is available for Microsoft Windows operating systems.
ZBServer Pro 1.5 has an unchecked buffer in the code that handles GET requests. This weakness allows for the execution of arbitrary code.
An attacker may supply a sequence of arbitrary characters as a GET request. When the length of the supplied string exceeds the size of the input buffer, the excess data will overwrite other variables on the stack and the stack frame itself.
Successful exploitation of this vulnerability could lead to a complete compromise of the target host.
Affected Products:
- ZBSoft ZBServer Pro 1.5.0
