TITLE

LAquis SCADA Input validation vulnerability

Trust: 0.8

sources: IVD: 7d851b30-463f-11e9-9851-000c29342cb1 // CNVD: CNVD-2019-02384

DESCRIPTION

LCDS Laquis SCADA prior to version 4.1.0.4150 allows execution of script code by opening a specially crafted report format file. This may allow remote code execution, data exfiltration, or cause a system crash. Script embedded in a crafted file can create files in arbitrary locations using the AddComboFile method. This vulnerability allows remote attackers to execute arbitrary code 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 MemoryWriteByte method. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the aq process. LAquis SCADA is a suite of SCADA software for monitoring and data acquisition. LCDS LAquis SCADA is prone to multiple security vulnerabilities. Failed attempts will likely cause a denial-of-service condition. LCDS LAquis SCADA version 4.1.0.3870 is vulnerable; other versions may also be affected
