CVE-2025-7962
Description
A flaw was found in com.sun.mail/jakarta.mail. The jakarta.mail component allows an attacker to inject SMTP messages by exploiting improper handling of carriage return and newline characters encoded in UTF-8. An unauthenticated attacker can leverage this vulnerability to send arbitrary SMTP messages. This injection occurs via crafted email content, potentially leading to unauthorized message transmission.
Statement
The assigned Moderate severity reflects that while the vulnerability can be exploited remotely, it requires an attacker to have some level of privilege on the system. The impact is primarily on the integrity of email messages, without affecting confidentiality or availability. This aligns with Red Hat's definition of a Moderate impact flaw, where exploitation is more difficult but could still lead to a compromise of resource integrity under specific circumstances.
This vulnerability affects Jakarta Mail v2.2. The affected version of Jakarta Mail is not shipped in Red Hat products.
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.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
