Description

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of LAquis SCADA Software. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the processing of the Memory.PChar method. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the aq process.
