CVE-2014-0771: Advantech WebAccess File and Directory Information Exposure

The BWOCXRUN.BwocxrunCtrl.1 control contains a method named “OpenUrlToBuffer.” This method takes a URL as a parameter and returns its contents to the caller in JavaScript. The URLs are accessed in the security context of the current browser session. The control does not perform any URL validation and allows “file://” URLs that access the local disk. The method can be used to open a URL (including file URLs) and read file URLs through JavaScript. This method could also be used to reach any arbitrary URL to which the browser has access.

Security readout for executives and security teams

This flaw lets a vulnerable Advantech WebAccess browser control read local files or reachable URLs through JavaScript in the user's browser session. For industrial environments, the concern is unauthorized exposure of sensitive workstation or network-accessible data rather than a confirmed public exploitation campaign. Exposure is most likely where Advantech WebAccess version 7.2 or other listed vulnerable deployments use the BWOCXRUN browser control on operator or engineering workstations. Treat as high priority for environments running affected WebAccess components, especially industrial systems with shared operator workstations or sensitive local files. Focus first on inventory, vendor guidance, and reducing access paths. Mitigation focus: Check Advantech and CISA guidance for the applicable fixed version or vendor mitigation.; Inventory WebAccess installations and identify use of the BWOCXRUN.BwocxrunCtrl.1 control.; Limit WebAccess access to trusted users and administrative networks only..

Insertion of Sensitive Information into Externally-Accessible File or Directory

Insertion of Sensitive Information into Externally-Accessible File or Directory represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
