A vulnerability classified as critical was found in Cisco Small Business RV110W, Small Business RV130, Small Business RV130W and Small Business RV215W (version now known). This vulnerability affects some unknown processing of the component Web-based Management Interface. The manipulation with an unknown input leads to a buffer overflow vulnerability. The CWE definition for the vulnerability is CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:
Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an authenticated, remote attacker to execute arbitrary code on an affected device or cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition. These vulnerabilities are due to insufficient validation of user fields within incoming HTTP packets. An attacker could exploit these vulnerabilities by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on an affected device with root-level privileges or to cause the device to restart unexpectedly, resulting in a DoS condition. To exploit these vulnerabilities, an attacker would need to have valid Administrator credentials on the affected device. Cisco has not released software updates that address these vulnerabilities.
The weakness was disclosed 07/21/2022 as cisco-sa-sb-rv-rce-overflow-ygHByAK. The advisory is available at tools.cisco.com. This vulnerability was named CVE-2022-20884 since 11/02/2021. The technical details are unknown and an exploit is not available.
