GLSA-200911-06 : PEAR Net_Traceroute: Command injection

critical Nessus Plugin ID 42916

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200911-06 (PEAR Net_Traceroute: Command injection)

 Pasquale Imperato reported that the $host parameter to the traceroute() function in Traceroute.php is not properly sanitized before being passed to exec().
 Impact :

 A remote attacker could exploit this vulnerability when user input is passed directly to PEAR Net_Traceroute in a PHP script, possibly resulting in the remote execution of arbitrary shell commands with the privileges of the user running the affected PHP script.
 Workaround :

 Ensure that all data that is passed to the traceroute() function is properly shell escaped (for instance using the escapeshellcmd() function).

Solution

All PEAR Net_Traceroute users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=dev-php/PEAR-Net_Traceroute-0.21.2'
