CVE-2022-41923: Grails Spring Security Core plugin: Improper Privilege Management vulnerability
Grails Spring Security Core plugin is vulnerable to privilege escalation. The vulnerability allows an attacker access to one endpoint (i.e. the targeted endpoint) using the authorization requirements of a different endpoint (i.e. the donor endpoint). In some Grails framework applications, access to the targeted endpoint will be granted based on meeting the authorization requirements of the donor endpoint, which can result in a privilege escalation attack. This vulnerability has been patched in grails-spring-security-core versions 3.3.2, 4.0.5 and 5.1.1. Impacted Applications: Grails Spring Security Core plugin versions: 1.x 2.x >=3.0.0 <3.3.2 >=4.0.0 <4.0.5 >=5.0.0 <5.1.1 We strongly suggest that all Grails framework applications using the Grails Spring Security Core plugin be updated to a patched release of the plugin. Workarounds: Users should create a subclass extending one of the following classes from the grails.plugin.springsecurity.web.access.intercept
package, depending on their security configuration: * AnnotationFilterInvocationDefinition
* InterceptUrlMapFilterInvocationDefinition
* RequestmapFilterInvocationDefinition
In each case, the subclass should override the calculateUri
method like so: @Override protected String calculateUri(HttpServletRequest request) { UrlPathHelper.defaultInstance.getRequestUri(request) }
This should be considered a temporary measure, as the patched versions of grails-spring-security-core deprecates the calculateUri
method. Once upgraded to a patched version of the plugin, this workaround is no longer needed. The workaround is especially important for version 2.x, as no patch is available version 2.x of the GSSC plugin.
Impact
The vulnerability allows an attacker access to one endpoint (i.e. the targeted endpoint) using the authorization requirements of a different endpoint (i.e. the donor endpoint). In some Grails framework applications using the Grails Spring Security Core (GSSC) plugin, access to the targeted endpoint will be granted based on meeting the authorization requirements of the donor endpoint, which can result in a privilege escalation attack.
Patches
The vulnerability has been patched in GSSC plugin versions 3.3.2, 4.0.5, and 5.1.1.
Workarounds
If you are unable to upgrade to a patched version of the plugin, the GSSC-CVE-2022-41923 repository contains workarounds for GSSC plugin versions 2.x through 5.x. The workaround is especially important for version 2.x, as no patch is available version 2.x of the GSSC plugin.
