Denial of Service Flaw in Siemens Automation License Manager

CVE-2011-4530

Summary

The Siemens Automation License Manager (ALM) versions 4.0 through 5.1+SP1+Upd1 contain a vulnerability that permits remote attackers to exploit improperly handled client fields. By sending excessively long input to specific functions such as open_session->workstation->NAME or grant->VERSION, an attacker can trigger a denial of service condition, leading to application crashes and interruptions in service. This vulnerability emphasizes the need for robust input validation and secure coding practices to mitigate potential exploitation.
