Advisories » CubeCart "_a" and "Submit" Parameter Handling Remote Cross-Site Scripting Vulnerabilities

Release Date:	26/03/2008	Severity:	Less Critical
SecWatch Advisory:	SWID1020752	Cause:	Input validation error
Solution Status:	Unpatched	Impact:	Cross Site Scripting
Exploit Status:	None Available	Access Vector:	From remote
Affected Software:	CubeCart 4.x
CVE:	CVE-2008-1550
Secunia:	SA29532
Bugtraq ID:	BID#28452

Description:

Two input validation vulnerabilities in CubeCart have been reported, which can be exploited by remote users to conduct cross-site scripting attacks.

User-supplied input passed to the "_a" and "Submit" parameters in index.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary script code in the security context of an affected website, as a result the code will be able to access any of the target user's cookies, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Affected:

CubeCart version 4.2.1. Other versions may also be affected.

Solution:

There was no vendor-supplied solution at the time of entry.

Edit source code manually to ensure user-supplied input is correctly sanitised.

Filter malicious characters and character sequences via a HTTP proxy or firewall with URL filtering capabilities.
