CVE-2023-27534

A path traversal vulnerability exists in curl <8.0.0 SFTP implementation causes the tilde (~) character to be wrongly replaced when used as a prefix in the first path element, in addition to its intended use as the first element to indicate a path relative to the user's home directory. Attackers can exploit this flaw to bypass filtering or execute arbitrary code by crafting a path like /~2/foo while accessing a server with a specific user.

Summary
  • (es) Una vulnerabilidad de salto de ruta existe en la implementación SFTP de curl anterior a 8.0.0 que causa que el carácter tilde (~) sea reemplazado incorrectamente cuando se usa como prefijo en el primer elemento de la ruta, además de su uso previsto como primer elemento para indicar una ruta relativa al directorio de inicio del usuario. Los atacantes pueden explotar esta falla para eludir el filtrado o ejecutar código arbitrario creando una ruta como /~2/foo al acceder a un servidor con un usuario específico.
