Vulnerability
CVE-2016-6139 is an improper access control vulnerability (CWE-284) in SAP TREX 7.10 – Revision 63. A specific function in the TREXNet communication protocol allows a remote unauthenticated attacker to read arbitrary files from the TREX server. The vulnerability is exploitable without authentication over the network [1][2].
Exploitation
An attacker can exploit this vulnerability by sending a crafted request to the vulnerable TREX service, which listens on a TCP port. No prior authentication or user interaction is required. The attacker only needs network access to the TREX server to trigger the file read operation [1][2].
Impact
Successful exploitation leads to disclosure of arbitrary files from the SAP TREX server. This can expose sensitive business information [1][2]. The impact is limited to confidentiality; integrity and availability are not affected as per Onapsis CVSS v3 scoring [2].
Mitigation
SAP released Security Note 2203591 to address this issue, which was made available on October 13, 2015. Administrators should apply the patch as soon as possible. No workarounds are documented in the available references [1][2].
