Known Issues

  • Bulk download generates a large amount of content in the tmp directory

In certain environments, an issue with the bulk download action causes the generation of a large amount of content in the KnowledgeTree temporary directory. Over an extended period of time the generated content may fill the relevant partition and prevent access to the repository. We have developed a patch to fix this issue.

  • Search for deleted, unarchived documents returns incorrect results

Search criteria isDeleted 'True' and isArchived 'False'. Related call: KTS-4205


  • On Linux, certain file types are downloaded and checked out as a zip archive

Note that is a Linux issue, and not a KnowledgeTree error. On RHEL, when checking out or downloading the following file types, the file is downloaded as a zip archive: docx, pptx, or other Office 2007 files. The file can be successfully checked back in to KnowledgeTree in this format. This issue is found to occur because the mime type magic is detecting the file as a zip file, which it is. Future updates to the mime type database will fix this issue on Linux. Related call: KTS-3623


  • Cross site request forgery and Web-based applications

Be aware that most web-based applications, including KnowledgeTree, may be vulnerable to cross-site-request-forgeries (CSRF). CSRF is entirely different to XSS – whereas CSRF exploits the trust a server places in a user, XSS exploits the trust a user places in the server. CSRF attacks are difficult to determine because the HTTP request containing the attack is sent by a trusted user. To reduce the risk of CSRF attacks, we strongly recommend that KnowledgeTree system administrators familiarize themselves with the issue of CSRF, and take the necessary precautions to protect their KnowledgeTree installations from such attacks.
