Summary

SMTP smuggling in Apache James

Details

Apache James prior to versions 3.8.1 and 3.7.5 is vulnerable to SMTP smuggling.

A lenient behaviour in line delimiter handling might create a difference of interpretation between the sender and the receiver which can be exploited by an attacker to forge an SMTP envelop, allowing for instance to bypass SPF checks.

The patch implies enforcement of CRLF as a line delimiter as part of the DATA transaction.

We recommend James users to upgrade to non vulnerable versions.

Severity

7.1 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
