CVE-2023-53962
Estado: ModificadaAlta (8.8)—
SOUND4 IMPACT/FIRST/PULSE/Eco v2.x contains an unauthenticated directory traversal vulnerability that allows remote attackers to write arbitrary files through the 'upgfile' parameter in upload.cgi. Attackers can exploit the vulnerability by sending crafted multipart form-data POST requests with directory traversal sequences to write files to unintended system locations.
CVSS
