Path Traversal in LAquis SCADA (LCDS) prior to 4.1.0.3237

IdentifiersCVE-2017-6020CWE-22· Improper Limitation of a Pathname…

CVE-2017-6020 is a path traversal vulnerability in Leao Consultoria e Desenvolvimento de Sistemas (LCDS) LTDA ME LAquis SCADA software, affecting all versions prior to 4.1.0.3237. The software fails to properly neutralize external input, allowing users to request absolute path sequences outside their privilege level. This enables remote attackers, with simple authentication, to access files outside of restricted directories, potentially exposing sensitive system or application files. The vulnerability is classified as CWE-22 (Improper Limitation of a Pathname to a Restricted Directory).

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows remote attackers to read arbitrary files outside of the intended directory, impacting confidentiality, integrity, and availability of the system. Attackers can leverage this to access sensitive information, modify files, or disrupt system operations. The vulnerability is easy to exploit and a public proof-of-concept is available, increasing the risk of widespread exploitation.

Mitigation

If you can’t patch tonight, do this now.

If immediate upgrade is not possible, restrict network access to the affected SCADA system, implement strong authentication controls, and monitor for suspicious file access patterns. Consider using application whitelisting and file system permissions to limit the impact of potential exploitation.

Remediation

Patch, then assume compromise.

Upgrade LAquis SCADA to version 4.1.0.3237 or later, which addresses the path traversal vulnerability by properly restricting file access to authorized directories.
