The SQL injection attack is one of the major threats to web applications. Through malicious inputs, attackers can cause data leakage and damage, and even remote code execution on the victim servers. A common solution is to use input sanitizers to filter out inputs that can result in SQL injection attacks. In this paper, we propose a novel solution, SQLR, to validate SQL sanitizers by systematically...
Debugging consumes significant time and effort in any major software development project. Moreover, even after the root cause of a bug is identified, fixing the bug is non-trivial. Given this situation, automated program repair methods are of value. In this paper, we present an automated repair method based on symbolic execution, constraint solving and program synthesis. In our approach, the requirement...
This article researches the applications of tree growth status tracking based on binocular vision. We conducted experiments using dual-camera of parallel optical axis to capture images, by the way of looking feature points calibrated in the tree's image to match the two images of trees. We calculated the spatial information change of the trees marked point within a certain time interval changes, and...
