Multiple vulnerabilities have been identified in freePBX, which could be exploited by remote attackers to execute arbitrary commands or scripting code.

The first vulnerability is caused by an input validation error in the "admin/modules/logfiles/asterisk-full-log.php" script when displaying logs, which could be exploited by attackers to cause arbitrary scripting code to be executed by the user's browser in the security context of an affected Web site.

The second issue is caused by an input validation error in the "admin/modules/music/page.music.php" script that does not validate the "del" parameter before being passed as an agument to an "exec()" call, which could be exploited by malicious administrators (or in conjunction with the first issue) to inject and execute arbitrary shell commands.
