Vulnerability Information

Severity: High
Vulnerability Published: N/A
Patch Published: 2007-10-05
CVE [?]: CVE-2007-5208
CPE [?]: cpe:/a:hp:linux_imaging_and_printing_project

Synopsis

The remote service allows for arbitrary command execution.

Description

The version of the HP Linux Imaging and Printing System hpssd daemon on the remote host fails to sanitize user-supplied input before appending it to a commandline when calling sendmail. Using a specially crafted email address, an unauthenticated, remote attacker can leverage this issue to execute arbitrary shell commands on the remote host subject to the permissions under which the daemon operates, typically root.

Solution

Upgrade to HPLIP 2.7.10 or later.
