Potential Security Impact: Remote Denial of Service (DoS)

Source: Hewlett-Packard Company, HP Software Security Response Team

VULNERABILITY SUMMARY
A potential vulnerability has been identified with HP Jetdirect running ftp. 
The vulnerability could be exploited remotely to create a Denial of Service 
(DoS).

References: none

SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.
HP Jetdirect running firmware versions from x.20.nn up to and including x.24.nn

BACKGROUND

The whitepaper 'HP Jetdirect Security Guidelines' has recommendations for 
securing HP Jetdirect.
The whitepaper is available here: 
http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00746792/c00746792.pdf

RESOLUTION

This vulnerability can be resolved by upgrading the Jetdirect firmware.
There is also a workaround for this vulnerability by making configuration 
changes.

Recent Jetdirect products use firmware revision x.25.nn or greater and are not 
vulnerable. Some older Jetdirect products allow the firmware to be upgraded and 
others do not.

Instructions for upgrading Jetdirect firmware are available here:
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=bpj07429

For J4169A 610n - upgrade the firmware to version L.25.nn or greater.

For J6057A 615n - upgrade the firmware to version R.25.nn or greater.

Other older Jetdirect products running versions from x.20.nn up to and 
including x.24.nn are potentially vulnerable. The firmware for these products 
cannot be upgraded. The potential vulnerability can be avoided by disabling ftp 
or using access control lists as discussed in the whitepaper 'HP Jetdirect 
Security Guidelines' mentioned above.
