Detailsinfo

A vulnerability was found in IBM Tealeaf CX up to 8.7. It has been classified as problematic. This affects an unknown functionality of the file download.php of the component Access Restriction. The manipulation of the argument log with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, and integrity. The summary by CVE is:

Directory traversal vulnerability in download.php in the Passive Capture Application (PCA) web console in IBM Tealeaf CX 7.x, 8.x through 8.6, 8.7 before FP2, and 8.8 before FP2 allows remote authenticated users to bypass intended access restrictions via a .. (dot dot) in the log parameter, as demonstrated using a crafted request for a customer-support file, as demonstrated by a log file.

The weakness was presented 03/06/2014 (Website). It is possible to read the advisory at tealeaf.support.ibmcloud.com. This vulnerability is uniquely identified as CVE-2013-6720 since 11/08/2013. The exploitability is told to be easy. It is possible to initiate the attack remotely. The successful exploitation needs a authentication. Technical details and a public exploit are known. The attack technique deployed by this issue is T1006 according to MITRE ATT&CK.

A public exploit has been developed by drone and been published 3 weeks after the advisory. The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k. By approaching the search of inurl:download.php it is possible to find vulnerable targets with Google Hacking.

The vulnerability is also documented in the databases at X-Force (89229), Exploit-DB (32546), SecurityFocus (BID 65987†) and Secunia (SA57238†). See VDB-66542 for similar entry. Be aware that VulDB is the high quality source for vulnerability data.
