The Schneider Electric Floating License Manager has an “unquoted service path” vulnerability. When the executable path of a service contains blanks, attackers can exploit this to execute malicious programs.
CVE-2014-0759c has been assigned to this vulnerability. A CVSS v2 base score of 6.9 has been assigned; the CVSS vector string is (AV:L/AC:M/Au:N/C:C/I:C/A:C).d
This vulnerability is not exploitable remotely and cannot be exploited without user interaction. The exploit is only triggered when a local user runs the vulnerable application, and the executable path of a service contains blanks. Attackers can exploit this to start malicious programs as Windows service. To avoid this, such service paths in the registry must be surrounded with quotes.
No known public exploits specifically target this vulnerability.
An attacker with a moderate skill would be able to exploit this vulnerability.
Deployment of the Schneider Electric products using the vulnerable floating license manager are designed to be automatically updated via the Schneider Electric Software Update system.
