-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 CVE-2010-3863: Apache Shiro information disclosure vulnerability Severity: Important Vendor: The Apache Software Foundation Versions Affected: Apache Shiro 1.0.0-incubating The unsupported JSecurity 0.9.x versions are also affected Description: Shiro's path-based filter chain mechanism did not normalize request paths before performing path-matching logic. The result is that Shiro filter chain matching logic was susceptible to potential path traversal attacks. Mitigation: All users should upgrade to 1.1.0 Example: For a shiro.ini [urls] section entry: /account/** = authc, ... /** = anon This states that all requests to the /account/** pages should be authenticated (as indicated by the 'authc' (authentication) filter) in the chain definition. A malicious request could be sent: GET /./account/index.jsp HTTP/1.1 And access would be granted because the path was not normalized to /account/index.jsp before evaluating the path for a match.
