CVE-2024-56195
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 · uneditedImproper Access Control vulnerability in Apache Traffic Server. This issue affects Apache Traffic Server: from 9.2.0 through 9.2.8, from 10.0.0 through 10.0.3. Users are recommended to upgrade to version 9.2.9 or 10.0.4, which fixes the issue.
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 confidenceImproper Access Control vulnerability in Apache Traffic Server allows unauthorized access or actions due to insufficient authorization checks. The vulnerability affects specific versions (9.2.0-9.2.8 and 10.0.0-10.0.3) and could allow attackers to bypass access controls in the proxy/cache system.

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.
-
Identify Apache Traffic Server versionRun `traffic_server -V` or check via package manager (`rpm -q trafficserver` / `dpkg -l trafficserver`)Affected if Version is 9.2.0 through 9.2.8, or 10.0.0 through 10.0.3 (falls in < 9.2.9 or < 10.0.4)
-
Confirm proxy or cache function is enabledCheck configuration file (records.config) for `proxy.config.http.enabled` or `proxy.config.cache.enabled` set to 1Affected if Proxy or cache functions are actively enabled on the server
-
Verify exposed network accessInspect `records.config` for `proxy.config.http.http_port` and check if the service is bound to an accessible network interface (not localhost-only)Affected if The proxy service listens on a reachable network address rather than localhost only
-
Review remap rules for access controlExamine `remap.config` for any rules that may be impacted by authorization bypassAffected if Remap rules exist that rely on access control without explicit authorization validation
Server is affected if it runs Apache Traffic Server version 9.2.0-9.2.8 or 10.0.0-10.0.3 with the proxy or cache function enabled and accessible over the network.
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 · scoped9.2.910.0.4
Upgrade Apache Traffic Server to version 9.2.9 or 10.0.4 to resolve the improper access control vulnerability.
Apache Traffic Server 9.2.9 (for 9.x users) or 10.0.4 (for 10.x users)
- 1. Identify the currently installed Apache Traffic Server version using 'traffic_server --version' or package manager
- 2. If running version 9.x (>=9.0.0, <9.2.9), plan upgrade to 9.2.9; if running version 10.x (>=10.0.0, <10.0.4), plan upgrade to 10.0.4
- 3. Create a full backup of the Traffic Server configuration directory (typically at /etc/trafficserver or /usr/local/etc/trafficserver)
- 4. Stop the Apache Traffic Server service using 'trafficctl stop' or system service manager
- 5. Upgrade the package using the system's package manager (e.g., 'apt upgrade', 'yum update', or compile from source using the fixed release tarball)
- 6. Verify the new version is installed: 'traffic_server --version' should show 9.2.9 or 10.0.4
- 7. Review the configuration for any deprecated settings specific to the new version
- 8. Start the Apache Traffic Server service and verify normal operation
