Title
Incorrect MAC key used in the RC4-MD5 ciphersuite
Summary
The OpenSSL 3.0 implementation of the RC4-MD5 ciphersuite incorrectly uses the AAD data as the MAC key. This makes the MAC key trivially predictable. An attacker could exploit this issue by performing a man-in-the-middle attack to modify data being sent from one endpoint to an OpenSSL 3.0 recipient such that the modified data would still pass the MAC integrity check. Note that data sent from an OpenSSL 3.0 endpoint to a non-OpenSSL 3.0 endpoint will always be rejected by the recipient and the connection will fail at that point. Many application protocols require data to be sent from the client to the server first. Therefore, in such a case, only an OpenSSL 3.0 server would be impacted when talking to a non-OpenSSL 3.0 client. If both endpoints are OpenSSL 3.0 then the attacker could modify data being sent in both directions. In this case both clients and servers could be affected, regardless of the application protocol. Note that in the absence of an attacker this bug means that an OpenSSL 3.0 endpoint communicating with a non-OpenSSL 3.0 endpoint will fail to complete the handshake when using this ciphersuite. The confidentiality of data is not impacted by this issue, i.e. an attacker cannot decrypt data that has been encrypted using this ciphersuite - they can only modify it. In order for this attack to work both endpoints must legitimately negotiate the RC4-MD5 ciphersuite. This ciphersuite is not compiled by default in OpenSSL 3.0, and is not available within the default provider or the default ciphersuite list. This ciphersuite will never be used if TLSv1.3 has been negotiated. In order for an OpenSSL 3.0 endpoint to use this ciphersuite the following must have occurred: 1) OpenSSL must have been compiled with the (non-default) compile time option enable-weak-ssl-ciphers 2) OpenSSL must have had the legacy provider explicitly loaded (either through application code or via configuration) 3) The ciphersuite must have been explicitly added to the ciphersuite list 4) The libssl security level must have been set to 0 (default is 1) 5) A version of SSL/TLS below TLSv1.3 must have been negotiated 6) Both endpoints must negotiate the RC4-MD5 ciphersuite in preference to any others that both endpoints have in common Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2).

An attacker could exploit this issue by performing a man-in-the-middle attack to modify data being sent from one endpoint to an OpenSSL 3.0 recipient such that the modified data would still pass the MAC integrity check. Note that data sent from an OpenSSL 3.0 endpoint to a non-OpenSSL 3.0 endpoint will always be rejected by the recipient and the connection will fail at that point. Many application protocols require data to be sent from the client to the server first. Therefore, in such a case, only an OpenSSL 3.0 server would be impacted when talking to a non-OpenSSL 3.0 client. If both endpoints are OpenSSL 3.0 then the attacker could modify data being sent in both directions. In this case both clients and servers could be affected, regardless of the application protocol. Note that in the absence of an attacker this bug means that an OpenSSL 3.0 endpoint communicating with a non-OpenSSL 3.0 endpoint will fail to complete the handshake when using this ciphersuite. The confidentiality of data is not impacted by this issue, i.e. an attacker cannot decrypt data that has been encrypted using this ciphersuite - they can only modify it. In order for this attack to work both endpoints must legitimately negotiate the RC4-MD5 ciphersuite. This ciphersuite is not compiled by default in OpenSSL 3.0, and is not available within the default provider or the default ciphersuite list. This ciphersuite will never be used if TLSv1.3 has been negotiated. In order for an OpenSSL 3.0 endpoint to use this ciphersuite the following must have occurred: 1) OpenSSL must have been compiled with the (non-default) compile time option enable-weak-ssl-ciphers 2) OpenSSL must have had the legacy provider explicitly loaded (either through application code or via configuration) 3) The ciphersuite must have been explicitly added to the ciphersuite list 4) The libssl security level must have been set to 0 (default is 1) 5) A version of SSL/TLS below TLSv1.3 must have been negotiated 6) Both endpoints must negotiate the RC4-MD5 ciphersuite in preference to any others that both endpoints have in common Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2)."

Un atacante podr\u00eda aprovechar este problema llevando a cabo un ataque de intermediario para modificar los datos que son enviados desde un endpoint a un destinatario de OpenSSL versi\u00f3n 3.0 de forma que los datos modificados sigan pasando la comprobaci\u00f3n de integridad MAC. Tenga en cuenta que los datos enviados desde un endpoint OpenSSL versi\u00f3n 3.0 a un endpoint no OpenSSL versi\u00f3n 3.0 siempre ser\u00e1n rechazados por el destinatario y la conexi\u00f3n fallar\u00e1 en ese punto. Muchos protocolos de aplicaci\u00f3n requieren que los datos sean enviados primero desde el cliente al servidor. Por lo tanto, en tal caso, s\u00f3lo un servidor OpenSSL versi\u00f3n 3.0 estar\u00eda afectado cuando hablara con un cliente no OpenSSL versi\u00f3n 3.0. Si ambos endpoints son OpenSSL versi\u00f3n 3.0, el atacante podr\u00eda modificar los datos que son enviados en ambas direcciones. En este caso, tanto los clientes como los servidores podr\u00edan verse afectados, independientemente del protocolo de aplicaci\u00f3n. Tenga en cuenta que, en ausencia de un atacante, este fallo significa que un endpoint de OpenSSL 3.0 que sea comunicado con un endpoint que no sea de OpenSSL 3.0 no podr\u00e1 completar el apret\u00f3n de manos cuando sea usado este cifrado. La confidencialidad de los datos no est\u00e1 afectada por este problema, es decir, un atacante no puede descifrar los datos que han sido encriptados usando este cifrado, s\u00f3lo puede modificarlos. Para que este ataque funcione, ambos endpoints deben negociar leg\u00edtimamente el cifrado RC4-MD5. Este ciphersuite no est\u00e1 compilado por defecto en OpenSSL versi\u00f3n 3.0, y no est\u00e1 disponible en el proveedor por defecto o en la lista de ciphersuite por defecto.

Para que un endpoint de OpenSSL versi\u00f3n 3.0 use esta ciphersuite debe haber ocurrido lo siguiente 1) OpenSSL debe haber sido compilado con la opci\u00f3n de tiempo de compilaci\u00f3n (no predeterminada) enable-weak-ssl-ciphers 2) OpenSSL debe tener el proveedor heredado cargado expl\u00edcitamente (ya sea a trav\u00e9s del c\u00f3digo de la aplicaci\u00f3n o por medio de la configuraci\u00f3n) 3) La ciphersuite debe haber sido a\u00f1adida expl\u00edcitamente a la lista de ciphersuite 4) El nivel de seguridad de libssl debe haber sido establecido en 0 (el valor predeterminado es 1) 5) Una versi\u00f3n de SSL/TLS inferior a TLSv1. 3 debe haber sido negociada 6) Ambos endpoints deben negociar el ciphersuite RC4-MD5 con preferencia a cualquier otro que ambos endpoints tengan en com\u00fan Corregido en OpenSSL versi\u00f3n 3.0.3 (Afectado 3.0.0,3.0.1,3.0.2)"
