CVE-2011-4534

Name of the Vulnerable Software and Affected Versions Ing. Punzenberger COPA-DATA zenon version 6.51 SP0

Description The issue allows remote attackers to cause a denial of service or possibly execute arbitrary code via a series of connections and disconnections on TCP port 1101.

Recommendations For version 6.51 SP0, consider restricting access to TCP port 1101 to minimize the risk of exploitation. As a temporary workaround, limiting the number of connections and disconnections on this port may help mitigate the issue. At the moment, there is no information about a newer version that contains a fix for this issue.
