CVE-2018-1199 spring-framework: Improper URL path validation allows for bypassing of security checks on static resources
Last modified: 2018-10-19 17:46:17 EDT
Spring Framework and Spring Security do not consider URL path parameters when processing security constraints. By adding a URL path parameter with special encodings, an attacker may be able to bypass a security constraint and access Spring MVC static resource URLs. Affected versions include: * Spring Security 4.1.0 - 4.1.4, 4.2.0 - 4.2.3 and 5.0 * Spring Framework 4.3.0 - 4.3.14, and 5.0.0 - 5.0.2 Older unmaintained versions of Spring Security and Spring Framework may also be affected. External References: https://pivotal.io/security/cve-2018-1199 Mitigation: As a general precaution, users are encouraged to separate public and private resources. For example, separating static resources and mapping them to /resources/public/** and /resources/private/** is preferred to having one common root with mixed public and private resource content underneath.

Jetty container in JBoss Fuse complies with servlet specification and does not return path parameters which is a root cause of this flaw, so JBoss Fuse is not affected.

For RH OpenStack Platform: Although the spring code contains the flaw, OpenDaylight uses Tomcat which is not vulnerable. "Tomcat follows the guidance previously provided by the Servlet Expert group and strips path parameters from the value returned by getContextPath(), getServletPath() and getPathInfo() [1]." [1] https://www.securityfocus.com/archive/1/archive/1/514517/100/0/threaded <-- 2010. catalina-7.0.27.1 used in ODL is from 2012 after the fixes. Should be ok.
Fixed upstream in Spring-security 5.0.1, 4.2.4, 4.1.5 via following commits: https://github.com/spring-projects/spring-security/commit/0eef5b4b425ab42b9fa0fde1a3f36a37b92558f2 https://github.com/spring-projects/spring-security/commit/cb8041ba67635edafcc934498ef82707157fd22a https://github.com/spring-projects/spring-security/commit/65da28e4bf62f58fb130ba727cbbd621b44a36d1
Spring Security is not used in Millicore component of RHMAP.
