Description
Weaver e-Bridge contains an unauthenticated arbitrary file read vulnerability that allows remote attackers to access arbitrary files on the host system by supplying a file: URL to the downloadUrl parameter of the saveYZJFile endpoint. Attackers can exploit this flaw to read sensitive files such as /etc/passwd or configuration and credential files, and the same endpoint's support for http(s) URLs also enables server-side request forgery against internal network resources. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-17.
