CRITICAL: Moderately critical
IMPACT: Security Bypass, DoS
WHERE: >From remote
SOFTWARE: Macromedia ColdFusion MX 7 http://secunia.com/product/4984/
DESCRIPTION: Two vulnerabilities have been reported in ColdFusion, which can be exploited by malicious, local users to bypass certain security restrictions and by malicious people to cause a DoS (Denial of Service).
1) It is possible to cause an infinite loop in ColdFusion by sending a specially crafted command to the ColdFusion Flash Remoting Gateway.
2) An error exists due to CFML templates outside a sandbox being able to call ColdFusion components within a sandbox in certain situations.
The vulnerabilities have been reported in versions 7 and 7.0.1.
SOLUTION: Update to version 7.0.2 or apply hotfixes for version 7.0.1: http://www.adobe.com/support/security/bulletins/hf701-apsb06-12.zip http://www.adobe.com/support/coldfusion/ts/documents/94491491/hf701-61892.zip
