Cisco Security Advisory
Apache Struts Remote Code Execution Vulnerability Affecting Cisco Products:
August 2018
Priority: Critical
Advisory ID: cisco-sa-20180823-apache-struts
First Published: 2018 August 23 20:00 GMT
Last Updated: 2018 September 13 14:38 GMT
Version 1.11: Final
Workarounds: No workarounds available
CVE-2018-11776
CWE-20
Summary
* A vulnerability in Apache Struts could allow an unauthenticated, remote
attacker to execute arbitrary code on a targeted system.
The vulnerability exists because the affected software insufficiently
validates user-supplied input, allowing the use of results with no
namespace value and the use of url tags with no value or action. In cases
where upper actions or configurations also have no namespace or a wildcard
namespace, an attacker could exploit this vulnerability by sending a
request that submits malicious input to the affected application for
processing. If successful, the attacker could execute arbitrary code in the
security context of the affected application on the targeted system.
The following Snort rules can be used to detect possible exploitation of
this vulnerability: Snort SID 29639, 39190, 39191, and 47634
