is vulnerable to attack via maliciously crafted Java-serialized objects and `javax.naming.Reference` instances. Several c3p0 `ConnectionPoolDataSource` implementations have a property called `userOverridesAsString` which conceptually represents a `Map<String,Map<String,String>>`. Prior to v0.12.0, that property was maintained as a hex-encoded serialized object. Any attacker able to reset this property, on an existing `ConnectionPoolDataSource` or via maliciously crafted serialized objects or `javax.naming.Reference` instances could be tailored execute unexpected code on the application's `CLASSPATH`. The danger of this vulnerability was strongly magnified by vulnerabilities in c3p0's main dependency, mchange-commons-java. This library includes code that mirrors early implementations of JNDI functionality, including ungated support for remote `factoryClassLocation` values. Attackers could set c3p0's `userOverridesAsString` hex-encoded serialized objects that include objects \"indirectly serialized\" via JNDI references. Deserialization of those objects and dereferencing of the embedded `javax.naming.Reference` objects could provoke download and execution of malicious code from a remote `factoryClassLocation`. Although hazard presented by c3p0's vulnerabilites are exarcerbated by vulnerabilities in mchange-commons-java, use of Java-serialized-object hex as the format for a writable Java-Bean property, of objects that may be exposed across JNDI interfaces, represents a serious independent fragility. The `userOverridesAsString` property of c3p0 `ConnectionPoolDataSource` classes has been reimplemented to use a safe CSV-based format, rather than rely upon potentially dangerous Java object deserialization. c3p0-0.12.0+ and above depend upon mchange-commons-java 0.4.0+, which gates support for remote `factoryClassLocation` values by configuration parameters that default to restrictive values. c3p0 additionally enforces the new mchange-commons-java `com.mchange.v2.naming.nameGuardClassName` to prevent injection of unexpected, potentially remote JNDI names. There is no supported workaround for versions of c3p0 prior to 0.12.0."}, {"lang": "es", "value": "c3p0, una biblioteca de pooling de conexiones JDBC, es vulnerable al ataque a trav\u00e9s de objetos serializados en Java creados maliciosamente e instancias de `javax.naming.Reference`. Varias implementaciones de `ConnectionPoolDataSource` de c3p0 tienen una propiedad llamada `userOverridesAsString` que representa conceptualmente un `Map&gt;`. Antes de la v0.12.0, esa propiedad se manten\u00eda como un objeto serializado codificado en hexadecimal. Cualquier atacante capaz de restablecer esta propiedad, en un `ConnectionPoolDataSource` existente o a trav\u00e9s de objetos serializados creados maliciosamente o instancias de `javax.naming.Reference`, podr\u00eda ser manipulado para ejecutar c\u00f3digo inesperado en el `CLASSPATH` de la aplicaci\u00f3n. El peligro de esta vulnerabilidad fue fuertemente magnificado por vulnerabilidades en la dependencia principal de c3p0, mchange-commons-java. Esta biblioteca incluye c\u00f3digo que refleja implementaciones tempranas de la funcionalidad JNDI, incluyendo soporte sin restricciones para valores remotos de `factoryClassLocation`. Los atacantes podr\u00edan establecer objetos serializados codificados en hexadecimal de `userOverridesAsString` de c3p0 que incluyen objetos 'serializados indirectamente' a trav\u00e9s de referencias JNDI. La deserializaci\u00f3n de esos objetos y la desreferenciaci\u00f3n de los objetos `javax.naming.Reference` incrustados podr\u00edan provocar la descarga y ejecuci\u00f3n de c\u00f3digo malicioso desde un `factoryClassLocation` remoto. Aunque el peligro presentado por las vulnerabilidades de c3p0 se ve exacerbado por las vulnerabilidades en mchange-commons-java, el uso de hexadecimal de objetos serializados en Java como formato para una propiedad Java-Bean escribible, de objetos que pueden ser expuestos a trav\u00e9s de interfaces JNDI, representa una grave fragilidad independiente. La propiedad `userOverridesAsString` de las clases `ConnectionPoolDataSource` de c3p0 ha sido reimplementada para usar un formato seguro basado en CSV, en lugar de depender de la deserializaci\u00f3n de objetos Java potencialmente peligrosa. c3p0-0.12.0+ y versiones superiores dependen de mchange-commons-java 0.4.0+, que restringe el soporte para valores remotos de `factoryClassLocation` mediante par\u00e1metros de configuraci\u00f3n que por defecto son valores restrictivos. c3p0 adicionalmente impone el nuevo `com.mchange.v2.naming.nameGuardClassName` de mchange-commons-java para prevenir la inyecci\u00f3n de nombres JNDI inesperados, potencialmente remotos. No hay soluci\u00f3n alternativa soportada para versiones de c3p0 anteriores a la 0.12.0."}], "lastModified": "2026-08-04T13:18:01.517", "sourceIdentifier": "security-advisories@github.com"}
