Overview<\/strong><\/p>\n

The Common Vulnerabilities and Exposures system has identified a significant vulnerability, CVE-2025-41248, within Spring Security’s annotation detection mechanism. This vulnerability, which primarily affects applications using Spring Security’s @EnableMethodSecurity feature, can potentially lead to an authorization bypass, compromising system security and leading to potential data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-41248
\nSeverity: High (CVSS Score: 7.5)
\nAttack Vector: Remote
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system compromise and data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Spring Security | All versions supporting @EnableMethodSecurity<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability stems from a flaw in the Spring Security annotation detection mechanism’s ability to resolve annotations on methods within type hierarchies with a parameterized super type with unbounded generics. This could potentially allow an attacker to bypass security measures by exploiting the incorrect resolution of annotations, specifically when using @PreAuthorize and other method security annotations.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Given the nature of the vulnerability, a direct exploit example might not be applicable. However, the vulnerability might be exploited in the context of a broader attack, such as a malicious user gaining access to sensitive data by bypassing authorization. Here’s an illustrative example:<\/p>\n

public abstract class GenericClass {\n@PreAuthorize(\"hasRole('ADMIN')\")\npublic abstract void sensitiveOperation(T data);\n}\npublic class ConcreteClass extends GenericClass {\n\/\/ The @PreAuthorize annotation is not correctly resolved here due to the vulnerability\npublic void sensitiveOperation(SomeType data) {\n\/\/ Implementation of sensitive operation\n}\n}<\/code><\/pre>\n
In this example, the attacker might exploit the vulnerability by invoking `sensitiveOperation` on an instance of `ConcreteClass`, bypassing the intended ‘ADMIN’ role restriction.<\/p>\n
Recommended Mitigation<\/strong><\/p>\n
To mitigate this vulnerability, the recommended course of action is to apply the vendor-supplied patch. In the absence of an immediate patch, employing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure.<\/p>\n","protected":false},"excerpt":{"rendered":"
