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 · unedited
SAP S/4HANA (SAP Enterprise Search for ABAP) contains a SQL injection vulnerability that allows an authenticated attacker to inject malicious SQL statements through user-controlled input. The application directly concatenates this malicious user input into SQL queries, which are then passed to the underlying database without proper validation or sanitization. Upon successful exploitation, an attacker may gain unauthorized access to sensitive database information and could potentially crash the application. This vulnerability has a high impact on the confidentiality and availability of the application, while integrity remains unaffected.

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 confidence

SQL injection vulnerability in SAP S/4HANA Enterprise Search for ABAP where authenticated attackers can inject malicious SQL statements through user-controlled input that is directly concatenated into SQL queries without validation or sanitization, potentially exposing sensitive database contents or causing application crashes.

MitigationImplement parameterized queries or prepared statements to safely handle user input in SQL queries, combined with input validation and proper escaping of special characters.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify SAP S/4HANA installation and version
    Execute transaction SM51 in SAP GUI to list installed SAP systems, or check the SAP system landscape directory (SLD). Verify the release version matches SAP S/4HANA (on-premise or cloud editions).
    Affected if The system is running SAP S/4HANA and the installed version falls within the affected range (if known) or is unpatched for this vulnerability.
  2. Determine if Enterprise Search is enabled
    Check SAP S/4HANA Enterprise Search configuration via transaction ESH_COCKPIT or by reviewing the enablement status in the SAP Fiori launchpad configuration. Alternatively, query table ESEARCH_CONFIG or related Enterprise Search metadata tables.
    Affected if Enterprise Search is actively enabled and processing search queries against ABAP-based data sources.
  3. Verify ABAP code for direct SQL concatenation in Enterprise Search
    Review ABAP code in the Enterprise Search namespace (package /ESH/) using transaction SE80 or SAAB. Search for dynamic SQL statements (EXEC SQL, Native SQL) where user input parameters are directly concatenated into the query string without using prepared statements or parameter binding.
    Affected if ABAP programs in the Enterprise Search layer contain dynamic SQL queries that directly concatenate user-supplied input without sanitization.
  4. Inspect input validation for Enterprise Search queries
    Examine the ABAP method classes handling Enterprise Search input (such as CL_ESH_SEARCH_ENGINE or related handler classes). Check whether CL_ABAP_CHAR_UTILITIES or validation methods are applied to user search terms before SQL execution.
    Affected if No input validation or sanitization routines are implemented for user search strings before they are used in SQL queries.
  5. Review system logs for SQL injection indicators
    Execute transaction SM37 or ST03N to review system logs. Search for SQL error messages (e.g., SQL error 914, 01000 series), unexpected syntax in WHERE clauses, or repeated failed SQL statements originating from Enterprise Search transactions.
    Affected if Logs show repeated SQL syntax errors or unusual SQL patterns in Enterprise Search executions that suggest injection attempts.

A defender is affected if their SAP S/4HANA system has Enterprise Search enabled and the ABAP code handling search queries directly concatenates user input into SQL without validation or parameterized queries.
