A vulnerability has been identified in SIMATIC WinAC RTX (F) 2010 (All versions < SP3 Update 1). Affected versions of the software contain a vulnerability that could allow an unauthenticated attacker to trigger a denial-of-service condition. The vulnerability can be triggered if a large HTTP request is sent to the executing service. The security vulnerability could be exploited by an attacker with network access to the affected systems. Successful exploitation requires no system privileges and no user interaction. An attacker could use the vulnerability to compromise availability of the service provided by the software.

Weakness

The product’s resource pool is not large enough to handle peak demand, which allows an attacker to prevent others from accessing the resource by using a (relatively) large number of requests for resources.
