Vulnerability from variot
Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV340 Series Routers could allow an authenticated, remote attacker with administrative credentials to execute arbitrary commands on the underlying operating system (OS) as a restricted user. For more information about these vulnerabilities, see the Details section of this advisory. Cisco Small Business RV340 A buffer error vulnerability exists in series routers.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Cisco RV340 routers. Authentication is required to exploit this vulnerability.The specific flaw exists within the handling of the fileparam parameter provided to the upload.cgi endpoint. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the www-data user
