DescriptionAbstract: Impact of CVE-2017-5638 on NetBackup OpsCenter Server
Severity: Security Vulnerability
Remote command execution(RCE) when performing file upload operation through NetBackup OpsCenter Web GUI.
More info: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-5638
The Apache Struts instance included in Veritas OpsCenter is susceptible to this vulnerability, such that an attacker could execute arbitrary commands through the OpsCenter WebServer Service. It may be possible to craft the Content-Type Header value to execute arbitrary commands on the underlying operating system. NOTE the impact of this vulnerability is low because the OpsCenter URLs where File Upload is used can only be accessed by an authenticated OpsCenter user.
NetBackup OpsCenter Server version 7.6 and later are affected by this vulnerability.
This vulnerability will be fixed in an upcoming release of OpsCenter.
Note: This vulnerability only affects OpsCenter Server. This vulnerability does not affect NetBackup software, OpsCenter Agent or OpsCenter ViewBuilder.
Please contact Veritas technical support, referencing this document and Etrack 3913550 (OpsCenter 8.0) and/or 3913549 (OpsCenter 7.7.3) to receive Emergency Engineering Binary (EEB) bundle(s) containing a fix for this issue.
If EEBs cannot be immediately applied to the OpsCenter server, please consider implementing the following workaround to mitigate this vulnerability until such time as they can be applied.
The issue is found in the Apache Struts 2 library that is used by the OpsCenter WebServer Service.
Stopping only the OpsCenter WebServer Service using a platform-specific command will avoid this vulnerability.
Note: Once this service is stopped, users will not be able to view or perform any operation via the OpsCenter Web UI.
Stopping the OpsCenter WebServer Service has NO impact on email notifications, scheduled reports, alert generation and data collection.
