| CVE ID | CVE-2022-20801 |
| CVSS SCORE | 4.3, AV:A/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L |
| AFFECTED VENDORS |
Cisco |
| AFFECTED PRODUCTS |
RV340 |
| VULNERABILITY DETAILS |
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Cisco RV340 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the handling of set-snmp JSON RPC requests. When parsing the usmUserAuthKey parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the www-data user. |
