Summary
Cisco Small Business RV Series Routers Command Injection Vulnerabilities

Notes

Summary
Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV340 and RV345 Routers could allow an authenticated, remote attacker to inject and execute arbitrary commands on the underlying operating system of an affected device. These vulnerabilities are due to insufficient validation of user-supplied input. An attacker could exploit these vulnerabilities by sending malicious input to an affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying Linux operating system of the affected device. To exploit these vulnerabilities, an attacker would need to have valid Administrator credentials on the affected device. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-smb-rv-cmd-inj-8Pv9JMJD ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-smb-rv-cmd-inj-8Pv9JMJD"]
Vulnerable Products
At the time of publication, these vulnerabilities affected the following Cisco Small Business RV Series Routers if they were running a vulnerable firmware release: RV340 Dual WAN Gigabit VPN Routers RV340W Dual WAN Gigabit Wireless-AC VPN Routers RV345 Dual WAN Gigabit VPN Routers RV345P Dual WAN Gigabit POE VPN Routers For information about which Cisco firmware releases were vulnerable at the time of publication, see the Fixed Software ["#fs"] section of this advisory.

Workarounds
There are no workarounds that address these vulnerabilities.
Fixed Software
When considering software upgrades ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page ["https://www.cisco.com/go/psirt"], to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers. Fixed Releases At the time of publication, the release information in the following table(s) was accurate. See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information. The left column lists Cisco software releases, and the right column indicates whether a release was affected by the vulnerabilities described in this advisory and which release included the fix for these vulnerabilities. Small Business RV340, RV340W, RV345, and R345P Routers Cisco Small Business Router Firmware Release First Fixed Release 1.0.03.26 and earlier 1.0.03.27 The Cisco Product Security Incident Response Team (PSIRT) validates only the affected and fixed release information that is documented in this advisory.
