Multiple Cisco products include an implementation of the Apache Struts 2 component that is affected by a remote command execution vulnerability.
The vulnerability is due to insufficient sanitization of user-supplied input. An attacker could exploit this vulnerability by sending crafted requests consisting of Object-Graph Navigation Language (OGNL) expressions to an affected system. An exploit could allow the attacker to execute arbitrary code on the targeted system.
Cisco has released software updates that address this vulnerability for all the affected products except Cisco Business Edition 3000. Cisco Business Edition 3000 customers should contact their Cisco representative for available options.
Workarounds that mitigate this vulnerability are not available. This advisory is available at the following link:

A vulnerability in the DefaultActionMapper component could allow an unauthenticated, remote attacker to execute arbitrary commands on the targeted system.
The vulnerability is due to insufficient sanitization of user-supplied input. An attacker could exploit this vulnerability by sending crafted requests consisting of Object-Graph Navigation Language (OGNL) expressions. An exploit could allow the attacker to execute arbitrary code on the targeted system.
The impact of this vulnerability on Cisco products varies depending on the affected product. Successful exploitation on Cisco ISE, Cisco Unified SIP Proxy, and Cisco Business Edition 3000 could result in an arbitrary command executed on the affected system. There is no authentication needed to execute the attack on Cisco ISE, Cisco Unified SIP Proxy and Cisco Unified CCE or Cisco PCCE. To exploit this vulnerability on Cisco Business Edition 3000, the attacker must provide valid credentials or persuade a user with valid credentials to execute a malicious URL.
Successful exploitation on the Cisco MXE 3500 Series could allow the attacker to redirect the user to a different and possibly malicious website; however, arbitrary command execution is not possible on this product.
See the "Vulnerability Scoring Details" section of this security advisory for additional information regarding the attack vector and impact.
This vulnerability is documented in Cisco bug IDs CSCui22841 (registered customers only) for Cisco ISE, CSCui33268 (registered customers only) for Cisco Business Edition 3000, CSCui40582 (registered customers only) for Cisco Unified SIP Proxy and CSCui48757 (registered customers only) for Cisco MXE 3500 Series, and CSCui51516 (registered customers only) for Cisco Unified CCE and Cisco PCCE.
This vulnerability has been assigned the Common Vulnerabilities and Exposures (CVE) ID CVE-2013-2251
