CVE-2022-41923: 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.
The exploitability of CVE-2022-41923 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
With low attack complexity and no required privileges, CVE-2022-41923 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2022-41923, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2022-41923, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.303% (probability of exploit)
EPSS Percentile: 69.92%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 30.08% of others.
