Vulnerabilidad alta de consumo de recursos en SiYuan anterior a v3.8.2

SiYuan versiones anteriores a v3.8.2 contiene una vulnerabilidad que permite a atacantes no autenticados consumir memoria ilimitada del servidor mediante solicitudes con rutas únicas, degradando la disponibilidad del servicio. Esta falla afecta principalmente a organizaciones en LATAM que utilizan SiYuan para gestión de notas y documentos internos. La vulnerabilidad puede ser explotada sin credenciales, permitiendo ataques de negación de servicio (DoS) contra instancias accesibles en red.

MOOS core-moos through 10.4.0 contains a denial of service vulnerability in MOOSCommServer::ListenLoop() where the accept thread performs a blocking receive without timeout during the wire-protocol handshake. An attacker can open a TCP connection to the MOOSDB port and send no data, causing the accept thread to block indefinitely while holding the socket-list lock, preventing all subsequent client…

Vulnerabilidad DoS en multer permite bloqueo de event loop en Node.js

multer, middleware popular para procesar multipart/form-data en Node.js, es vulnerable a ataques de denegación de servicio (DoS). Un atacante puede enviar solicitudes HTTP especialmente diseñadas con nombres de campo malformados que fuerzan al parser a iterar arreglos sparse de tamaño máximo, bloqueando el event loop e impidiendo que la aplicación procese otras peticiones. Afecta aplicaciones web en producción que usen multer para carga de archivos, especialmente relevante en empresas LATAM con infraestructura Node.js alta.

Vulnerabilidad en multer 2.2.0: descriptor de archivo no cerrado en cargas abortadas

multer, middleware de Node.js para procesar multipart/form-data, presenta una vulnerabilidad en la versión 2.2.0 donde las cargas abortadas o truncadas no cierran correctamente los descriptores de archivo, dejándolos abiertos en el sistema. Esto permite a atacantes remotos consumir recursos del servidor y potencialmente acceder a información sensible. El riesgo es alta en aplicaciones web que manejan uploads de usuarios sin autenticación robusta.

An unauthenticated attacker can send an IMAP ID command with a very large number of parameters before logging in, which causes memory and CPU usage to grow disproportionately. The login process can be terminated by the out-of-memory handling, which also terminates all other connections handled by the same process. This can cause degradation or denial of service for IMAP logins. Limit the number of…
