CVE-2024-40464
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue in beego v.2.2.0 and before allows a remote attacker to escalate privileges via the sendMail function located in beego/core/logs/smtp.go file
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA privilege escalation vulnerability exists in beego framework's logging SMTP functionality. The sendMail function in beego/core/logs/ssmtp.go contains a flaw that allows a remote attacker to elevate privileges, likely through improper authentication handling or input validation in the email sending mechanism.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if beego framework is in useSearch for 'beego' imports in your codebase or check go.mod for 'github.com/beego/beego/v2' dependencyAffected if beego is present as a dependency in the project
-
Identify the installed beego versionRun 'go list -m all | grep beego' or check go.mod for the exact version number (e.g., v2.2.0, v2.0.5)Affected if the version listed is less than v2.2.1 (e.g., v2.2.0, v2.0.x, v1.x)
-
Locate the SMTP logging configurationSearch configuration files or code for 'ssmtp', 'smtp', or 'logs' settings - typically in app.conf or configuration structs referencing beego/core/logsAffected if SMTP logging is configured with a sendMail function from beego/core/logs/ssmtp.go
-
Verify SMTP authentication configurationInspect the logging configuration for SMTP server credentials, username, password, or authentication settings used by the beego logging subsystemAffected if SMTP credentials are configured and the beego version is below v2.2.1
You are affected if beego version is below v2.2.1 AND the SMTP logging functionality (ssmtp.go) is in use with authentication configured.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.2.1
Upgrade to a patched version of beego beyond v2.2.0. If immediate upgrade is not feasible, restrict network access to SMTP servers and review any authentication credentials configured in the logging subsystem.
Beego v2.2.1
- Check current Beego version: go list -m all | grep beego
- Upgrade Beego to v2.2.1: go get github.com/beego/beego/[email protected]
- Update go.mod file if necessary: go mod tidy
- Verify the upgrade was successful: go list -m all | grep beego
- Rebuild and test the application to ensure compatibility
