Description
Deserialization of untrusted data vulnerability in QOS.CH Sarl logback logback-core (HardenedObjectInputStream (logback-core) modules) allows Object Injection, albeit heavily restricted.
More precisely, an attacker able to influence serialized data sent to
SimpleSocketServer or SimpleSSLSocketServer can instantiate Proxy objects.
Although deserialization is heavily restricted by HardenedObjectInputStream and no
practical way to achieve remote code execution or significant privilege
escalation has been identified, this issue constitutes a bypass of the
intended security restrictions.
This issue affects logback: through 1.5.33 inclusive.

Title: logback de QOS.CH Sarl, Description: Vulnerabilidad de deserialización de datos no confiables en QOS.CH Sarl logback logback-core (módulos HardenedObjectInputStream (logback-core)) permite la inyección de objetos, aunque muy restringida.
Más precisamente, un atacante capaz de influir en los datos serializados enviados a SimpleSocketServer o SimpleSSLSocketServer puede instanciar objetos Proxy.
Aunque la deserialización está muy restringida por HardenedObjectInputStream y no se ha identificado ninguna forma práctica de lograr la ejecución remota de código o una escalada significativa de privilegios, este problema constituye un bypass de las restricciones de seguridad previstas.
Este problema afecta a logback: hasta la versión 1.5.33 inclusive.
