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.
