Detailsinfo

A vulnerability was found in SAP HANA 1.0 (Database Software). It has been classified as critical. Affected is some unknown processing of the component HTTP/REST Endpoint Controller. The manipulation with an unknown input leads to a injection vulnerability (Log). CWE is classifying the issue as CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.
