Insights vulnerability analysis
Description
A vulnerability was found in Apache Sling Commons Messaging Mail(angus-mail), which provides a simple interface for sending emails via SMTPS in OSGi, does not offer an option to enable server identity checks, leaving connections vulnerable to "man-in-the-middle" attacks and can allow insecure email communication.
Statement
This vulnerability should be considered of important severity rather than moderate because it directly impacts the integrity and confidentiality of email communications over SMTPS. By disabling server identity checks, it leaves the communication channel vulnerable to "man-in-the-middle" (MITM) attacks, where an attacker could intercept, alter, or eavesdrop on email traffic by impersonating the legitimate mail server.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
