Security Bulletin: Apache Struts Vulnerability CVE-2017-9791 will not affect PSS products

Summary

The Struts 1 plugin in Apache Struts 2.3.x might allow remote code execution via a malicious field value passed in a raw message to the ActionMessage.

Among all the PSS products (LSF, PPM, RTM, PWS), only PWS 9.1 and 9.1.3 have Struts libs in the package. However, PWS will not use the libs even though they are there, so there is no risk that the vulnerability will be exploited. The struts/structs2 libs have been removed from the package for PWS 9.1.3.2 (which will be shipped with PSS 10.1). In other words, all the PSS products will not be affected by the vulnerability CVE-2017-9791.

The patch to remove Struts libs in PWS 9.1.3 has been released at patches/pws913/build149044 in SAS FTP Site.
