SECUNIA ADVISORY ID:
SA15278

VERIFY ADVISORY:
http://secunia.com/advisories/15278/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
4D WebSTAR V 5.x
http://secunia.com/product/2174/

DESCRIPTION:
Braden Thomas has reported a vulnerability in 4D WebSTAR, which can
be exploited by malicious people to cause a DoS (Denial of Service)
or potentially compromise a vulnerable system.

The vulnerability is caused due to a boundary error when processing
URLs in the web server's Tomcat plugin. This can be exploited to
cause a buffer overflow and crash a vulnerable service by sending a
specially crafted HTTP request with an overly long URL.

Successful exploitation may allow execution of arbitrary code.

The vulnerability has been reported in version 5.33 and 5.4. Other
versions may also be affected.

SOLUTION:
Disable the Tomcat plugin. This may affect the functionality.

PROVIDED AND/OR DISCOVERED BY:
