"The version of the Foscam IP Camera firmware 11.37.2.x < 11.37.2.49 on
the remote host has a directory traversal vulnerability.  A remote
attacker could exploit this to access the entire filesystem and wifi
credentials, for example, with a specially crafted request to retrieve
the host's /proc/kcore file. 

Note that Foscam cameras can be re-branded and re-sold by other vendors. 

Contact the vendor for vulnerability and firmware update information for
other firmware base versions.");
