Descriptions

In Linaro Automated Validation Architecture (LAVA) before 2022.11, users with valid credentials can submit crafted XMLRPC requests that cause a recursive XML entity expansion, leading to excessive use of memory on the server and a Denial of Service.

En Linaro Automated Validation Architecture (LAVA) anterior a 2022.11, los usuarios con credenciales válidas pueden enviar solicitudes XMLRPC manipuladas que provocan una expansión recursiva de la entidad XML, lo que provoca un uso excesivo de la memoria en el servidor y una Denegación de Servicio (DoS).

Igor Ponomarev discovered that LAVA, a continuous integration system for deploying operating systems onto physical and virtual hardware for running tests, was suspectible to denial of service via recursive XML entity expansion.
