ExpressionEngine Multiple Vulnerabilities

ExpressionEngine is prone to an HTTP-response-splitting vulnerability and a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input. An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user, steal cookie-based authentication credentials, and influence how web content is served, cached, or interpreted.

Mitigation:

Input validation should be used to ensure that untrusted data is not used to generate HTTP headers. Additionally, applications should use a whitelist of acceptable inputs that strictly conform to specifications.

ExpressionEngine is prone to an HTTP-response-splitting vulnerability and a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input.

An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user, steal cookie-based authentication credentials, and influence how web content is served, cached, or interpreted. This could aid in various attacks that try to entice client users into a false sense of trust.

ExpressionEngine 1.2.1 is vulnerable to these issues; other versions may also be affected.
