CVE-2024-40465
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 getCacheFileName function in file.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 confidenceThe vulnerability exists in the getCacheFileName function in beego's file.go (v2.2.0 and prior). This function handles cache file naming and appears to have a flaw that allows a remote attacker to manipulate cache file paths or names to achieve privilege escalation, likely through path traversal or improper input validation on cache file names.

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 installed beego versionRun 'go list -m all | grep beego' or check your go.mod file for the beego version entry. If using beego as a dependency, also check the version in your vendor directory or go.sum file.Affected if The installed version is 2.2.0 or any version prior to 2.2.1
-
Identify cache file usage in codeSearch your codebase for imports of beego cache modules: 'github.com/beego/beego/v2/core/cache' or references to 'getCacheFileName'. Check if your application initializes any cache using file-based caching.Affected if The application uses beego's cache module with file-based cache adapter, as the vulnerability is in the getCacheFileName function handling cache file paths
-
Inspect cache configurationLook for cache configuration in your beego configuration files (app.conf) or in code where cache is initialized. Search for 'cache' or 'FileCache' configuration settings.Affected if File-based cache is enabled and configured, meaning cache files are being written to disk with names generated by the vulnerable function
-
Check cache file permissionsInspect the directory where beego cache files are stored (typically in the app's working directory or temp directory). Run 'ls -la' on the cache directory to examine file ownership and permissions.Affected if Cache files are world-writable or accessible by lower-privileged users, which would allow exploitation of path traversal to escalate privileges
You are affected if your beego version is below 2.2.1 AND your application uses beego's file-based cache module, as the getCacheFileName vulnerability only applies when cache files are being created.
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 after v2.2.0. If upgrade is not immediately possible, review and sanitize all inputs to getCacheFileName function and restrict cache file write permissions to prevent unauthorized path manipulation.
2.2.1
- Check current Beego version by running: go list -m github.com/beego/beego/v2
- Upgrade to version 2.2.1 or later by running: go get github.com/beego/beego/[email protected]
- Run go mod tidy to update dependencies
- Run your application's test suite to verify functionality after upgrade
- Rebuild and redeploy your application
