evolution-data-server3 3.0.3 through 3.2.1 used insecure (non-SSL) connection when attempting to store sent email messages into the Sent folder, when the Sent folder was located on the remote server. An attacker could use this flaw to obtain login credentials of the victim.

Security readout for executives and security teams

Plain-English summary

CVE-2011-3355 is a legacy email-client data service flaw where affected Evolution Data Server versions could use a non-SSL connection when saving sent mail to a remote Sent folder. That could expose a user’s login credentials if the connection traffic was observed.

Executive priority

Treat this as a targeted legacy exposure issue, not a broad current emergency. Prioritize if the organization still uses old Evolution mail stacks or retains unmanaged Linux desktops that may handle corporate email credentials.

Technical view

The bundle identifies evolution-data-server3 versions 3.0.3 through 3.2.1. When the Sent folder was on a remote server, saving sent messages could occur over an insecure non-SSL connection, creating credential disclosure risk. No CVSS, CWE, or detailed fixed-version data is included.

Likely exposure

Exposure is likely limited to legacy Linux desktop environments running evolution-data-server3 3.0.3 through 3.2.1 with a remote server-hosted Sent folder. Organizations without this package, version range, or configuration are not shown as affected by the supplied sources.

Exploitation context

The provided bundle does not report active exploitation, and CISA KEV status is false. The practical risk is credential interception where non-SSL mail traffic can be observed. The sources do not provide exploit maturity, public exploit tooling, or incident evidence.

Researcher notes

The key missing data is severity scoring, CWE mapping, fixed version detail, and exploitation evidence. Analysis should stay tied to the narrow affected version range and remote Sent folder behavior described in the CVE bundle.

Mitigation direction

  • Inventory systems for evolution-data-server3 versions 3.0.3 through 3.2.1.
  • Check Debian, Red Hat, and OS vendor guidance for fixed packages.
  • Upgrade or remove affected evolution-data-server3 installations where present.
  • Require SSL/TLS for remote mail folder connections.
  • Consider credential rotation for users plausibly exposed over insecure networks.

Validation and detection

  • Confirm installed evolution-data-server3 package versions on Linux endpoints.
  • Identify users with Sent folders stored on remote mail servers.
  • Review mail account settings for non-SSL remote folder connections.
  • Verify vendor advisory status for each affected distribution.
  • Check logs or endpoint evidence for legacy Evolution usage during exposure windows.
