CVE-2015-7828
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 · uneditedSAP HANA Database 1.00 SPS10 and earlier do not require authentication, which allows remote attackers to execute arbitrary code or have unspecified other impact via a TrexNet packet to the (1) fcopydir, (2) fmkdir, (3) frmdir, (4) getenv, (5) dumpenv, (6) fcopy, (7) fput, (8) fdel, (9) fmove, (10) fget, (11) fappend, (12) fdir, (13) getTraces, (14) kill, (15) pexec, (16) stop, or (17) pythonexec method, aka SAP Security Note 2165583.
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 · high confidenceCritical authentication bypass in SAP HANA Database's TrexNet service (versions 1.00 SPS10 and earlier) allows unauthenticated remote attackers to execute arbitrary code via 17 exposed methods including file operations (fcopy, fput, fdel, fmove), process control (kill, pexec, stop), and code execution (pythonexec). The vulnerability requires no authentication, enabling complete system compromise through specially crafted TrexNet packets.

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 SAP HANA installation and versionRun 'HDB version' or check SAP HANA studio for the installed version. On Linux, also check /usr/sap/hdbversion or use the SAP HANA hdbsql command: 'select version from m_database;'. Compare the obtained version to 1.00 SPS10 or earlier.Affected if The installed version is 1.00 SPS10 or any version <= 1.00.
-
Verify TrexNet service statusCheck if the TrexNet service (nameserver, indexserver, or trex service) is running on the SAP HANA host. Use 'ps -ef | grep -i trex' or check SAP HANA administrator tools to confirm the service is active.Affected if The TrexNet service is running and exposed on the system.
-
Check TrexNet port exposureScan or inspect network listeners on the SAP HANA host for ports in the 3xx00 range (such as 30000, 30001, 31000, 31001). Use 'netstat -tulpn | grep -E "3[0-9]{4}"' or 'ss -tulpn' to identify listening ports. Verify if these ports are bound to 0.0.0.0 (all interfaces) rather than localhost only.Affected if Ports in the 3xx00 range are open and accessible from network interfaces other than localhost.
-
Confirm TrexNet authentication configurationReview SAP HANA configuration files or the trex.ini settings. Check if the security/authentication section has been modified from default. Inspect SAP Security Note 2165583 reference: authentication should be explicitly enabled on TrexNet. If the note was not applied, default configuration likely allows unauthenticated access.Affected if The TrexNet service accepts connections without requiring authentication (default vulnerable state before applying SAP Security Note 2165583).
A user is affected if SAP HANA version 1.00 SPS10 or earlier is installed AND the TrexNet service is running with accessible ports in the 3xx00 range AND authentication has not been explicitly enabled on the TrexNet service.

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 · scopedApply SAP Security Note 2165583 to enable authentication on the TrexNet service. Immediately restrict network access to TrexNet ports (3xx00 range) using firewalls or network segmentation until the patch is deployed.
SAP HANA 1.00 SPS11 or later
- Identify the current SAP HANA version using the HANA cockpit or running 'HDB version' command
- Confirm the SPS level by executing: SELECT * FROM M_SYSTEM_OVERVIEW in XS advanced
- Upgrade to SAP HANA SPS11 or later (SAP Security Note 2165583 addresses this authentication bypass)
- After upgrade, verify the TrexNet service requires authentication by reviewing the indexserver configuration
- Ensure network exposure of TrexNet port (3xx00-3xx15) is restricted to trusted internal networks only
- Validate the fix by attempting an unauthenticated TrexNet connection from an unauthorized host - this should now be rejected
