WebCalendar noSet variable overwrite
|webcalendar-noset-variable-overwrite (32832)||Medium Risk|
WebCalendar could allow a remote attacker to overwrite variables, caused by improper validation of unspecified parameters prior to being used with the noSet variable set. A remote attacker could exploit this vulnerability to overwrite certain configuration variables, which could lead to remote PHP file include vulnerabilities on the affected system.
Upgrade to the latest version of WebCalendar (1.0.5 or later), available from SourceForge.net: Files. See References.
For Debian Linux:
Refer to DSA-1267-1 for patch, upgrade, or suggested workaround information. See References.

- CVE-2007-1343: includes/functions.php in Craig Knudsen WebCalendar before 1.0.5 does not protect the noSet variable from external modification, which allows remote attackers to set arbitrary global variables via a URL with modified values in the noSet parameter, which leads to resultant vulnerabilities that probably include remote file inclusion and other issues.
