** DISPUTED ** In IQrouter through 3.3.1, the Lua function diag_set_password in the web-panel allows remote attackers to change the root password arbitrarily. Note: The vendor claims that this vulnerability can only occur on a brand-new network that, after initiating the forced initial configuration (which has a required step for setting a secure password on the system), makes this CVE invalid. This vulnerability is “true for any unconfigured release of OpenWRT, and true of many other new Linux distros prior to being configured for the first time”.

Comba AC2400 devices are prone to password disclosure via a simple crafted /09/business/upgrade/upcfgAction.php?download=true request to the web management server. The request doesn't require any authentication and will lead to saving the DBconfig.cfg file. At the end of the file, the login information is stored in cleartext.

D-Link DSL-2875AL and DSL-2877AL devices through 1.00.05 are prone to information disclosure via a simple crafted request to index.asp on the web management server because of username_v and password_v variables.

uhttpd in OpenWrt through 18.06.5 and 19.x through 19.07.0-rc2 has an integer signedness error. This leads to out-of-bounds access to a heap buffer and a subsequent crash. It can be triggered with an HTTP POST request to a CGI script, specifying both "Transfer-Encoding: chunked" and a large negative Content-Length value.

A memory corruption issue was addressed with improved input validation. This issue is fixed in iOS 12.4.7, watchOS 5.3.7. A remote attacker may be able to cause unexpected system termination or corrupt kernel memory.

Philips Hue Bridge model 2.X prior to and including version 1935144020 contains a Heap-based Buffer Overflow when handling a long ZCL string during the commissioning phase, resulting in a remote code execution.

FastTrack Admin By Request 6.1.0.0 supports group policies that are supposed to allow only a select range of users to elevate to Administrator privilege at will. If a user does not have direct access to the elevation feature through group policies, they are prompted to enter a PIN code in a challenge-response manner upon attempting to elevate privileges. The challenge's response uses a simple algorithm that can be easily emulated via data (customer ID and device name) available to all users, and thus any user can elevate to Administrator privilege.

Intelbras WRN240 devices do not require authentication to replace the firmware via a POST request to the incoming/Firmware.cfg URI.

The Broadcom brcmfmac WiFi driver prior to commit 1b5e2423164b3670e8bc9174e4762d297990deff is vulnerable to a heap buffer overflow. If the Wake-up on Wireless LAN functionality is configured, a malicious event frame can be constructed to trigger an heap buffer overflow in the brcmf_wowl_nd_results function. This vulnerability can be exploited with compromised chipsets to compromise the host, or when used in combination with CVE-2019-9503, can be used remotely. In the worst case scenario, by sending specially-crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. More typically, this vulnerability will result in denial-of-service conditions.
