The vulnerability identified as CVE-2013-10013 represents a critical sql injection flaw within the Bricco Authenticator Plugin, specifically targeting the authenticate/compare function in the DBAuthenticator.java file. This vulnerability resides in the src/java/talentum/escenic/plugins/authenticator/authenticators/ directory where user authentication mechanisms are implemented. The flaw allows malicious actors to manipulate the authentication process by injecting malicious sql code directly into the database query execution flow, potentially compromising the entire authentication system.
The technical implementation of this vulnerability stems from insufficient input validation and sanitization within the database authentication process. When the DBAuthenticator.java component processes user credentials, it fails to properly escape or parameterize user-supplied input before incorporating it into sql queries. This creates an environment where attackers can craft malicious input that alters the intended sql query structure, enabling unauthorized database access and potential data manipulation. The vulnerability operates at the application layer and specifically targets the database authentication mechanism, making it particularly dangerous for systems relying on this plugin for user access control.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it can lead to complete database compromise and potential lateral movement within affected systems. Attackers exploiting this vulnerability could retrieve sensitive user credentials, modify authentication records, or even execute administrative commands against the underlying database. The critical severity classification indicates that this flaw could be easily exploited and provides attackers with substantial privileges within the affected environment. Organizations using this plugin face significant risk of data breaches, credential theft, and potential system compromise that could affect multiple applications relying on the compromised authentication infrastructure.
Security mitigations for this vulnerability primarily involve upgrading to version 1.39 of the Bricco Authenticator Plugin, which contains the patch identified by the commit hash a5456633ff75e8f13705974c7ed1ce77f3f142d5. This upgrade addresses the root cause by implementing proper input validation and sql parameterization techniques that prevent malicious code injection. Organizations should also implement additional security measures including database query monitoring, input sanitization at multiple layers, and regular security assessments of authentication components. The vulnerability aligns with CWE-89 sql injection weakness and could be mapped to ATT&CK technique T1190 for exploitation of vulnerabilities in authentication systems, emphasizing the need for comprehensive defensive strategies.
