Name: Execution After Redirect (EAR)

The web application sends a redirect to another location, but instead of exiting, it executes additional code.

General Informations

Modes Of Introduction

Implementation

Common Consequences

Scope Impact Likelihood
Other
Confidentiality
Integrity
Availability		Alter Execution Logic, Execute Unauthorized Code or Commands

Note: This weakness could affect the control flow of the application and allow execution of untrusted code.

Observed Examples

References Description

CVE-2013-1402

Execution-after-redirect allows access to application configuration details.

CVE-2009-1936

chain: library file sends a redirect if it is directly requested but continues to execute, allowing remote file inclusion and path traversal.

CVE-2007-2713

Remote attackers can obtain access to administrator functionality through EAR.

CVE-2007-4932

Remote attackers can obtain access to administrator functionality through EAR.

CVE-2007-5578

Bypass of authentication step through EAR.

CVE-2007-2713

Chain: Execution after redirect triggers eval injection.

CVE-2007-6652

chain: execution after redirect allows non-administrator to perform static code injection.

Detection Methods

Black Box

This issue might not be detected if testing is performed using a web browser, because the browser might obey the redirect and move the user to a different page before the application has produced outputs that indicate something is amiss.

Vulnerability Mapping Notes

Justification : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comment : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
