Low 3.7
In plain English
A low-severity security flaw in TeleControl Server Basic from Siemens. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 39% of all known vulnerabilities).
Official description
A vulnerability has been identified in TeleControl Server Basic (All versions < V3.1.2.2). The affected product does not properly validate a length field in a serialized message which it uses to determine the amount of memory to be allocated for deserialization. This could allow an unauthenticated remote attacker to cause the application to allocate exhaustive amounts of memory and subsequently create a partial denial of service condition. Successful exploitation is only possible in redundant Telecontrol Server Basic setups and only if the connection between the redundant servers has been disrupted.
