Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVE-2017-10955

Severity High
Score 8.8/10

Summary

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of EMC Data Protection Advisor 6.3.0. Authentication is required to exploit this vulnerability. The specific flaw exists within the EMC DPA Application service, which listens on TCP port 9002 by default. When parsing the preScript parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute arbitrary code under the context of SYSTEM. Was ZDI-CAN-4697. NOTE: Dell EMC disputes that this is a vulnerability

CWE-78 - OS Command Injection

The OS command injection weakness (also known as shell injection) is a vulnerability which enables an attacker to run arbitrary OS commands on a server. This is done by modifying the intended downstream OS command and injecting arbitrary commands, enabling the execution of unauthorized OS commands. This has the potential to fully compromise the application along with all of its data, and, if the compromised process does not follow the principle of least privileges, it may compromise other parts of the hosting infrastructure as well. This weakness is listed as number ten in the 'CWE Top 25 Most Dangerous Software Weaknesses'.
