Hikvision Streaming Media Management Server v2.3.5 uses default credentials that allow remote attackers to authenticate and access restricted functionality. After authenticating with these credentials, an attacker can exploit an arbitrary file read vulnerability in the /systemLog/downFile.php endpoint via directory traversal in the fileName parameter. This exploit chain can enable unauthorized access to sensitive system 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.
