Title: TalentSoft Web+ WML Request Cookie Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
TalentSoft Web+ is an environment for developing web-based client/server applications. It will run on Microsoft Windows 9x/NT/2000 and Unix operating systems.
An exploitable buffer overflow has been discovered in Web+ when an oversized cookie is sent with a request for a WML file. This overflow could overwrite stack variables, including the return address, and be used to execute arbitrary code as the web server process. However, sending random data could cause the application to crash.
As the Web+ service runs with SYSTEM privileges under IIS 4, exploitation of arbitrary code will enable a remote attacker to fully compromise a host running the vulnerable software. Under IIS 5, IWAM_* privileges may be obtained with lesser consequences. Regardless, however, exploitation may allow local access to the vulnerable system.
Affected Products:
- TalentSoft Web+ Server 5.0.0
