CVE Published:

Summary

The SAP HANA extended application services 1.0 is prone to audit log injection vulnerabilities due to inadequate user input validation in specific HTTP/REST endpoints of the controller service. This lack of validation could enable unprivileged attackers to forge audit log entries, potentially compromising the reliability of log information. Additionally, the system's handling of user account and authentication logs reveals a similar flaw, as log entries miss escaping in the log file, leading to potential misinterpretation of audit records. While the syslog entries remain unaffected, the presence of unescaped logs could disrupt security audits and compliance efforts.

Affected Version(s)
