A vulnerability has been identified in SINUMERIK 808D V4.7 (All versions), SINUMERIK 808D V4.8 (All versions), SINUMERIK 828D V4.7 (All versions < V4.7 SP6 HF1), SINUMERIK 840D sl V4.7 (All versions < V4.7 SP6 HF5), SINUMERIK 840D sl V4.8 (All versions < V4.8 SP3). Specially crafted network packets sent to port 102/tcp (ISO-TSAP) could allow a remote attacker to either cause a Denial-of-Service condition of the integrated software firewall or allow to execute code in the context of the software firewall. The security vulnerability could be exploited by an attacker with network access to the affected systems on port 102/tcp. Successful exploitation requires no user privileges and no user interaction. The vulnerability could allow an attacker to compromise confidentiality, integrity and availability of the system. At the time of advisory publication no public exploitation of this security vulnerability was known
