Trust: 0.8

sources: JVNDB: JVNDB-2022-004941

DESCRIPTION

Multiple vulnerabilities in Cisco Small Business RV160, RV260, RV340, and RV345 Series Routers could allow an attacker to do any of the following: Execute arbitrary code Elevate privileges Execute arbitrary commands Bypass authentication and authorization protections Fetch and run unsigned software Cause denial of service (DoS) For more information about these vulnerabilities, see the Details section of this advisory. plural Cisco Small Business RV Series routers contain an out-of-bounds write vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Cisco RV340 routers. Authentication is not required to exploit this vulnerability.The specific flaw exists within the SSL VPN service, which listens on TCP port 8443 by default. 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 root
