D-Link DIR-615 Wireless N 300 Router allows authentication bypass via a modified POST request to login.cgi. This issue occurs because it fails to validate the password field. Successful exploitation of this issue allows an attacker to take control of the affected device.

A vulnerability, which was classified as critical, was found in LB-LINK BL-AC1900, BL-AC2100_AZ3, BL-AC3600, BL-AX1800, BL-AX5400P and BL-WR9000 up to 20250702. Affected is the function reboot/restore of the file /cgi-bin/lighttpd.cgi of the component Web Interface. The manipulation leads to improper authentication. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

A vulnerability has been identified in TIM 1531 IRC (All versions < V1.1). A remote attacker with network access to port 80/tcp or port 443/tcp could perform administrative operations on the device without prior authentication.

At the stage of publishing this security advisory no public exploitation is known. Siemens provides mitigations to resolve it.

NOTE: it was later reported that F5D7632-4V6 with firmware 6.01.08 is also affected.

It was discovered that the Western Digital My Cloud device before 2.30.196 is affected by an authentication bypass vulnerability. An unauthenticated attacker can exploit this vulnerability to authenticate as an admin user without needing to provide a password, thereby gaining full control of the device. (Whenever an admin logs into My Cloud, a server-side session is created that is bound to the user's IP address. After the session is created, it is possible to call authenticated CGI modules by sending the cookie username=admin in the HTTP request. The invoked CGI will check if a valid session is present and bound to the user's IP address.) It was found that it is possible for an unauthenticated attacker to create a valid session without a login. The network_mgr.cgi CGI module contains a command called "cgi_get_ipv6" that starts an admin session -- tied to the IP address of the user making the request -- if the additional parameter "flag" with the value "1" is provided. Subsequent invocation of commands that would normally require admin privileges now succeed if an attacker sets the username=admin cookie.

A vulnerability in the upgrade mechanism of Cisco collaboration products based on the Cisco Voice Operating System software platform could allow an unauthenticated, remote attacker to gain unauthorized, elevated access to an affected device. The vulnerability occurs when a refresh upgrade (RU) or Prime Collaboration Deployment (PCD) migration is performed on an affected device. When a refresh upgrade or PCD migration is completed successfully, an engineering flag remains enabled and could allow root access to the device with a known password. If the vulnerable device is subsequently upgraded using the standard upgrade method to an Engineering Special Release, service update, or a new major release of the affected product, this vulnerability is remediated by that action. Note: Engineering Special Releases that are installed as COP files, as opposed to the standard upgrade method, do not remediate this vulnerability. An attacker who can access an affected device over SFTP while it is in a vulnerable state could gain root access to the device. This access could allow the attacker to compromise the affected system completely.
