Published: Translated: NVD NIST

Summary

In SAP HANA extended application services 1.0, advanced model, there are two potential vulnerabilities related to audit log injection. Missing input validation in certain HTTP/REST endpoints may allow unprivileged attackers to forge audit log lines.

Risk Assessment

Unprivileged attackers may inject false data into audit logs, leading to misinterpretation of these logs and hindering incident detection.

Recommendation

It is recommended to implement input validation in HTTP/REST endpoints and ensure proper escaping of log entries to prevent unauthorized data injection.

Original NVD description (English source)

Two potential audit log injections in SAP HANA extended application services 1.0, advanced model: 1) Certain HTTP/REST endpoints of controller service are missing user input validation which could allow unprivileged attackers to forge audit log lines. Hence the interpretation of audit log files could be hindered or misdirected. 2) User Account and Authentication writes audit logs into syslog and additionally writes the same audit entries into a log file. Entries in the log file miss escaping. Hence the interpretation of audit log files could be hindered or misdirected, while the entries in syslog are correct.
