PEAR Net_Traceroute: Command injection

PEAR Net_Traceroute: Command injection An input sanitation error in PEAR Net_Traceroute might allow remote attackers to execute arbitrary commands. PEAR-Net_Traceroute 2009-11-26 2009-11-26 294264 remote 0.21.2 0.21.2

PEAR Net_Traceroute is an OS independent wrapper class for executing traceroute calls from PHP.

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

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.

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

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"
