Synopsis ========
An input sanitation error in PEAR Net_Traceroute might allow remote attackers to execute arbitrary commands.
Background ==========
PEAR Net_Traceroute is an OS independent wrapper class for executing traceroute calls from PHP.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-php/PEAR-Net_Traceroute < 0.21.2 >=3D 0.21.2
Description ===========
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).
Resolution ==========
All PEAR Net_Traceroute users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Ddev-php/PEAR-Net_Traceroute-0.21.2"
References ==========
