Vulnerability Note VU#693092
Caldera 9.20 contains multiple vulnerabilities
Caldera 9.20, and possibly earlier versions, contains multiple vulnerabilities.
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') - CVE-2014-2933
Caldera 9.20 and possibly earlier versions contains a path traversal vulnerability due to the script '/dirmng/index.php' caused by improper limitation of a pathname to a restricted directory. An attacker can exploit this vulnerability to access arbitrary directories on the server's operating system.
CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') - CVE-2014-2934
Caldera 9.20 and possibly earlier versions contains multiple script files that are vulnerable to a SQL injection due to improper neutralization of special elements used in an SQL command.
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') - CVE-2014-2935
Caldera CostView as part of Caldera 9.20 contains a vulnerability that allows an unauthenticated user the execution of OS commands.
The script '/costview3/xmlrpc_server/xmlrpc.php' is vulnerable to command execution due to improper neutralization of special elements used in an OS command. It can be triggered by submitting a specifically crafted PHP XMLRPC request by an unauthenticated remote user.
$ cat get_cutter_tools.xml
$ curl --data @get_cutter_tools.xml http://<host>/costview3/xmlrpc_server/xmlrpc.php
CWE-627 - Dynamic Variable Evaluation - CVE-2014-2936
Caldera 9.20 and possibly earlier versions contains a directory manager component of Caldera 9.20 that allows the manipulation of variables in the global scope. There are various scripts that are vulnerable to global variable scope injection:
This can be exploited by overwriting defined variables with arbitrary values during script runtime. This can be used to enable the upload function to store code within the web root directory structure. This results in an arbitrary code execution on the server.
The CVSS score below was calculated for CVE-2014-2935.
An unauthenticated attacker could access arbitrary directories on the server's operating system, access arbitrary database data, execute OS commands, or manipulate global variables.
We are currently unaware of a practical solution to this problem.
As a general good security practice, only allow connections from trusted hosts and networks.
