CVE-2023-36921
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 Solution Manager (Diagnostics agent) - version 7.20, allows an attacker to tamper with headers in a client request. This misleads SAP Diagnostics Agent to serve poisoned content to the server. On successful exploitation, the attacker can cause a limited impact on confidentiality and availability of the application.
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 header injection/tampering vulnerability in SAP Solution Manager Diagnostics Agent version 7.20 allows attackers to manipulate client request headers, causing the agent to serve poisoned content to the backend server. This leads to limited impact on confidentiality and availability of the application.

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.
-
Confirm SAP Solution Manager Diagnostics Agent is installedLocate the Diagnostics Agent installation directory or check installed SAP software components for 'SAP Solution Manager Diagnostics Agent'Affected if The Diagnostics Agent is not present on the system, the vulnerability does not apply
-
Identify the installed Diagnostics Agent versionUse SAP software inventory tools or check the agent's version information file to determine the exact version numberAffected if The installed version is exactly 7.20, making it vulnerable to this CVE
-
Verify HTTP connectivity is enabled on the agentCheck the Diagnostics Agent configuration for HTTP listener settings or web service endpoints that accept client requestsAffected if HTTP/web connectivity is disabled, the header injection vector is not reachable
-
Inspect header handling configurationReview agent configuration files or settings related to HTTP header processing, proxy settings, or request forwardingAffected if Header validation is disabled or absent, allowing manipulation of request headers
-
Check agent logs for suspicious header activityReview Diagnostics Agent log files for entries showing unexpected or tampered HTTP headers in requestsAffected if Logs contain evidence of header tampering or unusual header values in forwarded requests
A system is affected if SAP Solution Manager Diagnostics Agent version 7.20 is installed with HTTP connectivity enabled, allowing external attackers to manipulate request headers.
