Unauthenticated Configuration File Exposure via Predictable URL in DB-70 / CVE pending

Delta Dore DB-70 is Industrial IP Controller

The Delta Dore DB-70 stores its configuration on a static path on the web server. The naming structure for the configuration file is "DB-70_WSA_" + "Application Version without dots" + "_config.bin". For instance, if the application version is 01.04.00, the configuration file would be named "DB-70_WSA_010104_config.bin" .

http://xx.yy.zz.tt:8080/admin/DB-70_WSA_010104_config.bin

The DB-70 device exposes its application version on the "informations.shtm" web page without requiring any authentication. As a result, anyone can easily retrieve the device's application version.
Consequently, an unauthenticated attacker can easily construct a URL to retrieve the device's configuration file without any authentication.

This configuration file contains the username and password in plain text, posing a significant security risk. It exposes the device to potential denial-of-service attacks and unauthorized takeover.

Another issue that introduces a vulnerability in the system is the overlooked username "install," which has a default password of "install" as well. Administrators are often unaware of this user, which has the ability to modify certain critical DB-70 settings.

AvediaServer Unauthorised API Access Vulnerability

Image
Two weeks ago I discovered a security vulnerability in AvediaServer, details of which you can see below. VITEC (formerly Exterity) AvediaServer uses API to list, create and delete users. On the other hand, as you can see, they forgot to implement any authentication to this API. So, if you send the following GET requests to AvediaServer, you can see all users, individual user details with encrypted password (if the user is local) and profiles (admin, asset manager, etc.). Platform details where I found this vulnerability. AvediaServer Product : avsrv-m8105 Platform : mavsrv-c1520 Version : 8.6.2-1 http://hostname/api/auth/users http://hostname/api/auth/users/1 http://hostname/api/auth/profiles You can also create a user with administrative access if you send a POST request using the following parameters. I also used Shodan and Google Dorking and found several devices open to the internet. I found asset owners based on IP address records and I informed them. ...

IP-COM Multi-WAN Hotspot Router (M50) Vulnerability / CVE pending

Image
IP-COM Multi-WAN Hotspot Router (M50) allow unauthenticated remote attackers to access the configuration file and consequently bypass authentication by directly requesting either http://xxx.yyy.zzz.qqq/cgi-bin/DownloadCfg/RouterCfm.cfg or http://xxx.yyy.zzz.qqq/cgi-bin/DownloadCfg/switch.cfg. The configuration file contains the administrator password encoded in Base64. A remote attacker can easily decode the administrator password, set up a VPN server, infiltrate the victim's network, and alter DNS records to manipulate requests, redirecting users to malicious sites. Model: Multi-WAN Hotspot Router M50 Version: V15.01.0.5(3076_839) Cumhur Kizilari
