[SA17756] ClientExec Multiple SQL Injection Vulnerabilities

From: Secunia Security Advisories (sec-advsecunia.com)
Date: Tue Nov 29 2005 - 04:02:16 CST

TITLE:
ClientExec Multiple SQL Injection Vulnerabilities

SECUNIA ADVISORY ID:
SA17756

VERIFY ADVISORY:
http://secunia.com/advisories/17756/

CRITICAL:
Less critical

IMPACT:
Manipulation of data

WHERE:
From remote

SOFTWARE:
ClientExec 2.x
http://secunia.com/product/4074/

DESCRIPTION:
r0t has reported some vulnerabilities in ClientExec, which can be
exploited by malicious users to conduct SQL injection attacks.

Input passed to the "frmClientID", "billshowid", and "billdetailid"
parameters in "index.php" isn't properly sanitised before being used
in a SQL query. This can be exploited to manipulate SQL queries by
injecting arbitrary SQL code.

Example:
http://[host]/index.php?action=0&billdetailid=30&billshowid=[sql]
http://[host]/index.php?action=0&billdetailid=[sql]&billshowid=-1
http://[host]/index.php?frmClientID=[sql]

The vulnerabilities have been reported in version 2.3. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
