Cisco Device Manager contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system. Updates are available.
A vulnerability in the Java Archive (JAR) executable files that are downloaded using the Java Network Launching Protocol (JNLP) from the Cisco MDS 9000 Series or Cisco Nexus 5000 Series Switches could allow an unauthenticated, remote attacker to execute arbitrary commands on the client host that is executing the JNLP file. Command execution would occur with the privileges of the user.
The vulnerability is due to insufficient validation of certain parameters passed by the element-manager.jnlp file and executed by the affected JAR files. An attacker may exploit this vulnerability by redirecting the user to download a crafted version of the element-manager.jnlp file and execute the file.
Cisco has confirmed the vulnerability in a security advisory and has released software updates.
Systems that have downloaded Cisco Device Manager versions prior to 5.2.8 from devices running Cisco NX-OS Software or Cisco MDS 9000 NX-OS Software are vulnerable.
To exploit the vulnerability, the attacker may provide a file to the user and persuade the user to open or execute the file by using misleading language or instructions.
Cisco Device Manager runs on end-user systems and is downloaded from devices running Cisco NX-OS Software or Cisco MDS 9000 NX-OS Software. Only end-user systems running Cisco Device Manager are vulnerable; devices running Cisco NX-OS Software or Cisco MDS 9000 NX-OS Software are not affected by this vulnerability.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary commands on a targeted system with the privileges of the user. If the user holds elevated privileges, the attacker could completely compromise the system.
The vulnerability is due to improper input sanitization of user-supplied values by the affected software when handling the element-manager.jnlp file.
An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to download and run a maliciousJNLP file on an affected system. When run, the file could supply malicious commands to the targeted system, where the commands could be executed in the security context of the user. If the user holds elevated privileges, the attacker could completely compromise the system.
