Directory traversal vulnerability exists in a-blog cms Ver.3.1.x series Ver.3.1.9 and earlier, Ver.3.0.x series Ver.3.0.30 and earlier, Ver.2.11.x series Ver.2.11.59 and earlier, Ver.2.10.x series Ver.2.10.51 and earlier, and Ver.2.9 and earlier versions. If this vulnerability is exploited, a user with editor or higher privilege who can login to the product may obtain arbitrary files on the server including password files.
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.
