Schneider Electric Wonderware Information Server (WIS) Portal 4.0 SP1 through 5.5 allows remote attackers to read arbitrary files or cause a denial of service via an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.
CVE 해결 방법
Schneider Electric has created an update for WIS web pages and
components to address the vulnerabilities listed in this advisory.
Customers using all versions of WIS are affected and should upgrade to
WIS Version 5.5 and then apply the security update.
Customers using the affected versions of WIS should set the security
level settings in the Internet browser to “Medium – High” to minimize
the risks presented by these vulnerabilities. In addition, the
Wonderware Information Server Portal can be configured to use HTTPS that
will require additional steps as documented in the products user
documentation.
Schneider Electric has released a security bulletin titled “Multiple
Vulnerabilities in Wonderware Information Server LFSEC00000102” to
announce the security update, which is available at the following
location:
