CVE Name:CVE-2009-1357
An HTTP Response Splitting vulnerability [1] [2] has been discovered in Sun Java System Delegated Administrator. HTTP Response Splitting occurs when an attacker has the possibility of injecting a carriage return (0x0D) or a line feed (0x0A) character sequence into the HTTP headers of the web server’s response. This allows proxy cache-poisoning attacks that affect the proxy users base when requesting a web page that belongs to the affected domain, redirection attacks or other kind of Cross-Site Scripting attacks.
Sun Microsystems has published a Sun Alert for this issue. It has been assigned the ID 255928.
This vulnerability was discovered by the Security Consulting Services team from Core Security.
