Critical Security Vulnerabilities Discovered in Netcomm and TP-Link Routers

Security vulnerabilities have been disclosed in Netcomm and TP-Link routers, some of which could be weaponized to achieve remote code execution. The flaws, tracked as CVE-2022-4873 and CVE-2022-4874, concern a case of stack-based buffer overflow and authentication bypass and impact Netcomm router...

CVE-2022-4873

On Netcomm router models NF20MESH, NF20, and NL1902 a stack based buffer overflow affects the sessionKey parameter. By providing a specific number of bytes, the instruction pointer is able to be overwritten on the stack and crashes the application at a known location...

Stack overflow

On Netcomm router models NF20MESH, NF20, and NL1902 a stack based buffer overflow affects the sessionKey parameter. By providing a specific number of bytes, the instruction pointer is able to be overwritten on the stack and crashes the application at a known location...

Authentication flaw

Authentication bypass in Netcomm router models NF20MESH, NF20, and NL1902 allows an unauthenticated user to access content. In order to serve static content, the application performs a check for the existence of specific characters in the URL .css, .png etc. If it exists, it performs a "fake logi...

CVE-2022-4873

CVE-2022-4873 is a stack-based buffer overflow in the Netcomm NF20MESH, NF20, and NL1902 sessionKey handling that can overwrite the instruction pointer and crash the app. Related CVE-2022-4874 is an authentication bypass; together these flaws enable remote code execution when exploited in affecte...

CVE-2022-4874 Authenticated bypass in Netcomm router models NF20MESH, NF20, and NL1902 allows unauthenticated user to get access to content.

Authentication bypass in Netcomm router models NF20MESH, NF20, and NL1902 allows an unauthenticated user to access content. In order to serve static content, the application performs a check for the existence of specific characters in the URL .css, .png etc. If it exists, it performs a "fake logi...

CVE-2022-4874

CVE-2022-4874 affects Netcomm NF20MESH, NF20 and NL1902 router models. An authentication bypass exists where the app serves static content by checking the URL for specific characters (e.g., .css, .png) and performing a “fake login” to grant a active session, allowing unauthenticated access to con...
