Security News > 2021 > February > Critical Flaws Reported in Cisco VPN Routers for Businesses—Patch ASAP

Cisco has rolled out fixes for multiple critical vulnerabilities in the web-based management interface of Small Business routers that could potentially allow an unauthenticated, remote attacker to execute arbitrary code as the root user on an affected device.
The flaws - tracked from CVE-2021-1289 through CVE-2021-1295 - impact RV160, RV160W, RV260, RV260P, and RV260W VPN routers running a firmware release earlier than Release 1.0.01.02.
Along with the aforementioned three vulnerabilities, patches have also been released for two more arbitrary file write flaws affecting the same set of VPN routers that could have made it possible for an adversary to overwrite arbitrary files on the vulnerable system.
All the nine security issues were reported to the networking equipment maker by security researcher Takeshi Shiomitsu, who has previously uncovered similar critical flaws in RV110W, RV130W, and RV215W Routers that could be leveraged for remote code execution attacks.
While exact specifics of the vulnerabilities are still unclear, Cisco said the flaws -.
Separately, another set of five glitches in the web-based management interface of Small Business RV016, RV042, RV042G, RV082, RV320, and RV325 routers could have granted an attacker the ability to inject arbitrary commands on the routers that are executed with root privileges.
