Networking products major Cisco Systems has mentioned it does not plan to resolve a critical security vulnerability influencing some of its Compact Small business routers, instead urging consumers to switch the equipment.
The bug, tracked as CVE-2021-1459, is rated with a CVSS score of 9.8 out of 10, and impacts RV110W VPN firewall and Compact Business enterprise RV130, RV130W, and RV215W routers, allowing an unauthenticated, remote attacker to execute arbitrary code on an affected equipment.
The flaw, which stems from incorrect validation of consumer-equipped input in the web-based administration interface, could be exploited by a destructive actor to mail specially-crafted HTTP requests to the specific machine and accomplish distant code execution.
” A productive exploit could let the attacker to execute arbitrary code as the root user on the underlying working process of the affected product,” Cisco claimed in its advisory.
Security researcher Treck Zhou has been credited with reporting the vulnerability. Even though the business pointed out there is been no proof of energetic exploitation tries in the wild, it would not intend to release a patch or make any workarounds accessible, citing that the goods have arrived at close-of-lifetime.
“The Cisco Little Business RV110W, RV130, RV130W, and RV215W Routers have entered the end-of-daily life course of action,” the company explained. “Buyers are inspired to migrate to the Cisco Smaller Organization RV132W, RV160, or RV160W Routers.”
Individually, Cisco has also released program updates to handle numerous vulnerabilities in Cisco SD-WAN vManage Program (CVE-2021-1137, CVE-2021-1479, and CVE-2021-1480) that could permit an unauthenticated, distant attacker to execute arbitrary code or permit an authenticated, neighborhood attacker to get escalated privileges on an impacted program.
As a end result of a buffer overflow situation, CVE-2021-1479 is rated 9.8 in severity, effective exploitation of which “could allow the attacker to execute arbitrary code on the fundamental functioning technique with root privileges.”
