In Advantech WebAccess versions V8.2_20170817 and prior, WebAccess versions V8.3.0 and prior, WebAccess Dashboard versions V.2.0.15 and prior, WebAccess Scada Node versions prior to 8.3.1, and WebAccess/NMS 2.0.3 and prior, a path transversal vulnerability has been identified, which may allow an attacker to execute arbitrary code. En Advantech WebAccess en versiones V8.2_20170817 y anteriores, WebAccess en versiones V8.3.0 y anteriores, WebAccess Dashboard en versiones V.2.0.15 y anteriores, WebAccess Scada Node en versiones anteriores a la 8.3.1 y WebAccess/NMS 2.0.3 y anteriores, se ha identificado una vulnerabilidad de salto de directorio que podría permitir que un atacante ejecute código arbitrario. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. • http://www.securityfocus.com/bid/104190 https://ics-cert.us-cert.gov/advisories/ICSA-18-135-01 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
