Pivotal Spring Security OAuth Open Redirector Vulnerability



A vulnerability in Pivotal Spring Security OAuth could allow an unauthenticated, remote attacker to conduct an open redirect attack on a targeted system.

The vulnerability is due to insufficient validation of user-supplied input by the affected software. An attacker could exploit this vulnerability by sending a request using the authorization code grant type to the targeted system and specifying a malicious redirection URI using the redirect_url parameter. A successful exploit could cause the authorization server to redirect the resource owner user-agent to an attacker-controlled URI, providing the attacker with sensitive information (such an authorization code) which could be used to conduct further attacks.

Pivotal Software has confirmed the vulnerability and released software updates.
