  ChaiVM Multiple Security Vulnerabilities
------------------------------------------------------------------------

SUMMARY

 <http://www.hp.com/products1/embedded/products/platform/chaivm.html>
ChaiVM is used in networked appliances such as printers, mobile computing
devices, and other mobile or fixed networked embedded hardware. Two
security vulnerabilities in the product have been found allowing any
network user to add additional Chai Services to the product (compromising
the security of the product).

DETAILS

Vulnerable systems:
 * Hewlett Packard (HP) ChaiVM
 * HP 9000
 * HP 4100
 * HP 45nn
 * HP 8150
(Possibly others using ChaiVM)

HP Bug ID:
Not assigned

CERT Vulnerability ID:
780747

Two vulnerabilities exist.
1. Access to the file system hosting ChaiVM will allow any user to add,
delete, or modify services hosted by the ChaiServer. This is especially
applicable in cases where the file is accessible through the network using
PJL (Printer Job Language).

2. The default loader (this.loader) verifies JAR signatures. However, HP
released an advanced loader (EZloader, this.ez), which in turn, does not
verify signatures for new services.
