first spoke of it: Improper Encoding or Escaping of Output vulnerability in elixir-tesla tesla allows multipart part header injection via unescaped Content-Disposition parameter values. Tesla.Multipart.part_headers_for_disposition/1 interpolates each disposition parameter as #{k}="#{v}" with no validation of CR (\r), LF (\n), or double-quote characters. The values come verbatim from the caller via Tesla.Multipart.add_field/4 (the name parameter), Tesla.Multipart.add_file/3, and Tesla.Multipart.add_file_content/4 (both the filename parameter and other disposition opts). A " in the value closes the quoted parameter early; a \r\n ends the Content-Disposition header line and starts a new part header (such as a forged Content-Type), or, after a second \r\n, ends the entire part header block and prepends bytes to the part body. The default-filename path in add_file/3 derives the filename via Path.basename/1, which does not strip CR or LF, so any application forwarding a partially-attacker-controlled file path inherits the same issue. This issue affects tesla: from 0.8.0 before 1.18.3.

What it is to other things

affects	elixir-tesla/tesla NVD
made_by	elixir-tesla NVD

In words only, so not counted until a person confirms one:

made_by	`elixir_tesla` NVD says “elixir-tesla”
affects	`elixir_tesla/tesla` NVD says “elixir-tesla · tesla”

Una ' en el valor cierra el parámetro entre comillas prematuramente; un \\r\\n termina la línea del encabezado Content-Disposition y comienza un nuevo encabezado de parte (como un Content-Type falsificado), o, después de un segundo \\r\\n, termina todo el bloque de encabezados de parte y antepone bytes al cuerpo de la parte.

Una ' en el valor cierra el parámetro entre comillas prematuramente; un \\r\\n termina la línea del encabezado Content-Disposition y comienza un nuevo encabezado de parte (como un Content-Type falsificado), o, después de un segundo \\r\\n, termina todo el bloque de encabezados de parte y antepone bytes al cuerpo de la parte. La ruta de nombre de archivo predeterminada en add_file/3 deriva el nombre de archivo a través de Path.basename/1, que no elimina CR o LF, por lo que cualquier aplicación que reenvíe una ruta de archivo parcialmente controlada por el atacante hereda el mismo problema.\n\nEste problema afecta a tesla: desde 0.8.0 antes de 1.18.3."

The default-filename path in add_file/3 derives the filename via Path.basename/1, which does not strip CR or LF, so any application forwarding a partially-attacker-controlled file path inherits the same issue.\n\nThis issue affects tesla: from 0.8.0 before 1.18.3."

The values come verbatim from the caller via Tesla.Multipart.add_field/4 (the name parameter), Tesla.Multipart.add_file/3, and Tesla.Multipart.add_file_content/4 (both the filename parameter and other disposition opts). A \" in the value closes the quoted parameter early; a \\r\\n ends the Content-Disposition header line and starts a new part header (such as a forged Content-Type), or, after a second \\r\\n, ends the entire part header block and prepends bytes to the part body. The default-filename path in add_file/3 derives the filename via Path.basename/1, which does not strip CR or LF, so any application forwarding a partially-attacker-controlled file path inherits the same issue.\n\nThis issue affects tesla: from 0.8.0 before 1.18.3."

Los valores provienen textualmente del llamador a través de Tesla.Multipart.add_field/4 (el parámetro 'name'), Tesla.Multipart.add_file/3, y Tesla.Multipart.add_file_content/4 (tanto el parámetro 'filename' como otras opciones de disposición). Una ' en el valor cierra el parámetro entre comillas prematuramente; un \\r\\n termina la línea del encabezado Content-Disposition y comienza un nuevo encabezado de parte (como un Content-Type falsificado), o, después de un segundo \\r\\n, termina todo el bloque de encabezados de parte y antepone bytes al cuerpo de la parte. La ruta de nombre de archivo predeterminada en add_file/3 deriva el nombre de archivo a través de Path.basename/1, que no elimina CR o LF, por lo que cualquier aplicación que reenvíe una ruta de archivo parcialmente controlada por el atacante hereda el mismo problema.\n\nEste problema afecta a tesla: desde 0.8.0 antes de 1.18.3."

The values come verbatim from the caller via Tesla.Multipart.add_field/4 (the name parameter), Tesla.Multipart.add_file/3, and Tesla.Multipart.add_file_content/4 (both the filename parameter and other disposition opts). A \" in the value closes the quoted parameter early; a \\r\\n ends the Content-Disposition header line and starts a new part header (such as a forged Content-Type), or, after a second \\r\\n, ends the entire part header block and prepends bytes to the part body. The default-filename path in add_file/3 derives the filename via Path.basename/1, which does not strip CR or LF, so any application forwarding a partially-attacker-controlled file path inherits the same issue.\n\nThis issue affects tesla: from 0.8.0 before 1.18.3."

Los valores provienen textualmente del llamador a través de Tesla.Multipart.add_field/4 (el parámetro 'name'), Tesla.Multipart.add_file/3, y Tesla.Multipart.add_file_content/4 (tanto el parámetro 'filename' como otras opciones de disposición). Una ' en el valor cierra el parámetro entre comillas prematuramente; un \\r\\n termina la línea del encabezado Content-Disposition y comienza un nuevo encabezado de parte (como un Content-Type falsificado), o, después de un segundo \\r\\n, termina todo el bloque de encabezados de parte y antepone bytes al cuerpo de la parte. La ruta de nombre de archivo predeterminada en add_file/3 deriva el nombre de archivo a través de Path.basename/1, que no elimina CR o LF, por lo que cualquier aplicación que reenvíe una ruta de archivo parcialmente controlada por el atacante hereda el mismo problema.\n\nEste problema afecta a tesla: desde 0.8.0 antes de 1.18.3."

The values come verbatim from the caller via Tesla.Multipart.add_field/4 (the name parameter), Tesla.Multipart.add_file/3, and Tesla.Multipart.add_file_content/4 (both the filename parameter and other disposition opts). A \" in the value closes the quoted parameter early; a \\r\\n ends the Content-Disposition header line and starts a new part header (such as a forged Content-Type), or, after a second \\r\\n, ends the entire part header block and prepends bytes to the part body. The default-filename path in add_file/3 derives the filename via Path.basename/1, which does not strip CR or LF, so any application forwarding a partially-attacker-controlled file path inherits the same issue.\n\nThis issue affects tesla: from 0.8.0 before 1.18.3."

Los valores provienen textualmente del llamador a través de Tesla.Multipart.add_field/4 (el parámetro 'name'), Tesla.Multipart.add_file/3, y Tesla.Multipart.add_file_content/4 (tanto el parámetro 'filename' como otras opciones de disposición). Una ' en el valor cierra el parámetro entre comillas prematuramente; un \\r\\n termina la línea del encabezado Content-Disposition y comienza un nuevo encabezado de parte (como un Content-Type falsificado), o, después de un segundo \\r\\n, termina todo el bloque de encabezados de parte y antepone bytes al cuerpo de la parte. La ruta de nombre de archivo predeterminada en add_file/3 deriva el nombre de archivo a través de Path.basename/1, que no elimina CR o LF, por lo que cualquier aplicación que reenvíe una ruta de archivo parcialmente controlada por el atacante hereda el mismo problema.\n\nEste problema afecta a tesla: desde 0.8.0 antes de 1.18.3."

The values come verbatim from the caller via Tesla.Multipart.add_field/4 (the name parameter), Tesla.Multipart.add_file/3, and Tesla.Multipart.add_file_content/4 (both the filename parameter and other disposition opts). A \" in the value closes the quoted parameter early; a \\r\\n ends the Content-Disposition header line and starts a new part header (such as a forged Content-Type), or, after a second \\r\\n, ends the entire part header block and prepends bytes to the part body. The default-filename path in add_file/3 derives the filename via Path.basename/1, which does not strip CR or LF, so any application forwarding a partially-attacker-controlled file path inherits the same issue.\n\nThis issue affects tesla: from 0.8.0 before 1.18.3."

Los valores provienen textualmente del llamador a través de Tesla.Multipart.add_field/4 (el parámetro 'name'), Tesla.Multipart.add_file/3, y Tesla.Multipart.add_file_content/4 (tanto el parámetro 'filename' como otras opciones de disposición). Una ' en el valor cierra el parámetro entre comillas prematuramente; un \\r\\n termina la línea del encabezado Content-Disposition y comienza un nuevo encabezado de parte (como un Content-Type falsificado), o, después de un segundo \\r\\n, termina todo el bloque de encabezados de parte y antepone bytes al cuerpo de la parte. La ruta de nombre de archivo predeterminada en add_file/3 deriva el nombre de archivo a través de Path.basename/1, que no elimina CR o LF, por lo que cualquier aplicación que reenvíe una ruta de archivo parcialmente controlada por el atacante hereda el mismo problema.\n\nEste problema afecta a tesla: desde 0.8.0 antes de 1.18.3."
