We have always believed that reliable vulnerability intelligence and tools to aid identifying and fixing vulnerabilities should be freely available for consumers to ensure that users, who care about their online privacy and security, can stay secure. Only a few vendors address vulnerabilities in a proper way and help users get updated and stay secure. End-users (whether private individuals or businesses) are otherwise left largely alone, and that is why back in 2002, Secunia Research started investigating, coordinating disclosure and verifying software vulnerabilities. In 2016, Secunia Research became a part of Flexera and today our in-house software vulnerability research remains the core of the Software Vulnerability Management products at Flexera. https://www.flexera.com/enterprise/company/about/secunia-research/ The public Secunia Advisory database contains information for researchers, security enthusiasts, and consumers to lookup individual products and vulnerabilities and assess, whether they need to take any actions to secure their systems or whether a given vulnerability has already been discovered https://secuniaresearch.flexerasoftware.com/community/advisories/ == 9) Verification Please verify this advisory by visiting the Secunia Research website: https://secuniaresearch.flexerasoftware.com/secunia_research/2018-2 ==

It enables quality assurance teams to create and manage their test cases as well as to organize them into test plans. These test plans allow team members to execute test cases and track test results dynamically." Source: https://github.com/TestLinkOpenSourceTRMS/testlink-code Business recommendation: SEC Consult advises to immediately install the available updates as attackers might gain access to sensitive data belonging to other users. A thorough security review performed by security professionals is highly recommended in order to identify potential further security deficiencies. Vulnerability overview/description: --- 1) Insecure Direct Object Reference An unauthenticated user can gain access to referenced files which are produced by different test cases. By using a simple ID iterator, all produced output data can be gathered from the whole system. The actual impact strongly depends on the classification of the produced data which is referenced. Therefore, the risk can vary from low to critical depending on the use case. Proof of concept: - 1) Insecure Direct Object Reference An unauthenticated attacker can download data from the TestLink environment by using the following url: http:///lib/attachments/attachmentdownload.php?skipCheck=1= The tag specifies the target address and can also include a sub- folder where the hosted TestLink application is located. Vulnerable / tested versions: - The following versions have been tested and are vulnerable. It is assumed that older versions are affected as well, e.g.: * 1.9.16 * 1.9.15 * 1.9.14 Vendor contact timeline: 2017-10-18: Contacting vendor through http://mantis.testlink.org Vendor requested the information. 2017-10-19: Asked if the advisory should be uploaded to mantis directly. 2017-10-21: Contact agreed. 2017-10-23: Uploaded the advisory to mantis. 2017-11-01: Contact provided a fix for 1.9.16.
