CVE-2019-13915 Information

Description

b3log Wide before 1.6.0 allows three types of attacks to access arbitrary files. First the attacker can write code in the editor and compile and run it approximately three times to read an arbitrary file. Second the attacker can create a symlink and then place the symlink into a ZIP archive. An unzip operation leads to read access and write access (depending on file permissions) to the symlink target. Third the attacker can import a Git repository that contains a symlink similarly leading to read and write access.
