Description
A path injection vulnerability exists in OpenPLC v3 (2c82b0e79c53f8c1f1458eee15fec173400d6e1a) as the binary program compiled from glue_generator.cpp does not perform any validation on the file path parameters passed via the command line. The user-controlled input parameters are directly passed to the underlying file operation functions (fopen/ifstream/ofstream) for file reading and writing. An attacker can exploit this vulnerability by constructing a malicious path to read arbitrary readable files.
There is a path injection vulnerability in OpenPLC-v3, which arises from the program not performing any validity checks on the file path parameters passed in from the command line. Attackers can read any readable file by constructing malicious paths, posing a risk of information leakage.
