S

erver-Side Request Forgery (SSRF) in Apache HTTP Server on Windows allows to potentially leak NTLM hashes to a malicious server via  mod_rewrite or apache expressions that pass unvalidated request input. This issue affects Apache HTTP Server: from 2.4.0 through 2.4.63. Note:  The Apache HTTP Server Project will be setting a higher bar for accepting vulnerability reports regarding SSRF via UNC paths. The server offers limited protection against administrators directing the server to open UNC paths. Windows servers should limit the hosts they will connect over via SMB based on the nature of NTLM authentication.

Summary
  • (es) Server-Side Request Forgery (SSRF) en Apache HTTP Server en Windows permite filtrar hashes NTLM a un servidor malicioso mediante mod_rewrite o expresiones de Apache que pasan una entrada de solicitud no validada. Este problema afecta al servidor HTTP Apache desde la versión 2.4.0 hasta la 2.4.63. Nota: El proyecto del servidor HTTP Apache establecerá un estándar más estricto para la aceptación de informes de vulnerabilidad relacionados con SSRF mediante rutas UNC. El servidor ofrece protección limitada contra administradores que le indiquen que abra rutas UNC. Los servidores Windows deben limitar los hosts a los que se conectan mediante SMB según la naturaleza de la autenticación NTLM.
