Wind River Systems VxWorks debug service enabled by default



Vendor Statement

Security Advisory Report - OBSO-1010-01

Enabled VxWorks debug service
Creation Date: 2010-10-15
Last Update: 2010-10-15

A security researcher has identified a large number of products based on the VxWorks platform provided by Wind River Systems with a debug service enabled by default at port 17185/udp.

Vulnerability Details
The debug service provides full access to the memory of an affected device and allows for memory to be written as well as functions to be called. Of the various products based on VxWorks, the following are not affected by this vulnerability: HiPath Wireless Convergence, RG 8700, optiPoint 410/420 SIP and HFA (V5).

Affected Products

    • HiPath 3000 (HG 1500 Gateway)
    • HiPath 4000 (HG 35xx Gateway)
    • optiPoint 410/420 HFA, versions before V5
    • optiPoint 600 office

Recommended Actions
In general, it is recommended not to attach the mentioned systems directly at the internet. Appropriate firewall rules should be implemented to restrict access to the debug service (17185/udp).

The problem is solved in the following versions; an update to these or higher versions is highly recommended:
    • HiPath 3000 V8: V8 R5.2.0
    • HiPath 4000 V4: V4 R4.1.12
    • HiPath 4000 V5: V5 R1.2.4

Please note:
    • HiPath 3000 V7: You need to upgrade the HG 1500 gateway only. Please use V8 R5.2.0 for this. You may keep the system itself in V7.
    • HiPath 3000 V6 and earlier have reached end of SW support; please consider an upgrade to V7 or V8
    • HiPath 4000 V3 and earlier have reached end of SW support; please consider an upgrade to V4 or higher.
    • Some older, unsupported versions of optiPoint 410/420 HFA IP phones are also vulnerable. Please ensure, that V5 is installed on all phones.
    • optiPoint 600 office has reached end of life since a few years already; an update is unfortunately not available
