A vulnerability, which was classified as critical, was found in ATutor up to 2.2.1 (Learning Management Software). This affects an unknown functionality of the file /mods/_core/courses/users/create_course.php. The manipulation of the argument icon
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 exists in ATutor before 2.2.2 via the icon parameter to /mods/_core/courses/users/create_course.php. The attacker can read an arbitrary file by visiting get_course_icon.php?id= after the traversal attack.
