Vulnerability from cvelistv5 – Published: 2017-06-24 00:00 – Updated: 2024-08-05 17:18 Disputed
VLAI Shadowserver Previdian
Summary
/cgi-bin/wapopen in Boa 0.94.14rc21 allows the injection of "../.." using the FILECAMERA variable (sent by GET) to read files with root privileges. NOTE: multiple third parties report that this is a system-integrator issue (e.g., a vulnerability on one type of camera) because Boa does not include any wapopen program or any code to read a FILECAMERA variable.
