The vulnerability in the implementation of the SMTP protocol on email servers allows attackers to circumvent the SPF security policy and send hidden HTTP requests (HTTP Request Smuggling attack).

The vulnerability of the SMTP protocol implementation in email servers is related to the lack of checks for the integrity of messages during the processing of the . sequence. Exploiting this vulnerability allows a malicious actor to bypass the SPF security policy and send hidden HTTP requests HTT...

Amazon Linux 2 : golang (ALAS-2024-2388)

The version of golang installed on the remote host is prior to 1.20.12-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2388 advisory. A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response body to read many...

Medium: golang

Issue Overview: A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response body to read many more bytes from the network than are in the body. A malicious HTTP client can further exploit this to cause a server to automatically read a large amount of da...

Postfix through 3.8.5 allows SMTP smuggling unless configured with smtpd_data_restrictions=reject_unauth_pipelining and smtpd_discard_ehlo_keywords=chunking (or certain other options that exist in recent versions). Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address allowing bypass of an SPF protection mechanism. This occurs because Postfix supports <LF>.<CR><LF> but some other popular e-mail servers do not. To prevent attack variants (by always disallowing <LF> without <CR>) a different solution is required such as the smtpd_forbid_bare_newline=yes option with a Postfix minimum version of 3.5.23 3.6.13 3.7.9 3.8.4 or 3.9.
