Security vulnerabilities have been disclosed in Netcomm and TP-Link routers, a few of which may very well be weaponized to attain distant code execution.
The flaws, tracked as CVE-2022-4873 and CVE-2022-4874, concern a case of stack-based buffer overflow and authentication bypass and influence Netcomm router fashions NF20MESH, NF20, and NL1902 operating firmware variations sooner than R6B035.
“The two vulnerabilities, when chained collectively, allow a distant, unauthenticated attacker to execute arbitrary code,” the CERT Coordination Center (CERT/CC) stated in an advisory printed Tuesday.
“The attacker can first acquire unauthorized entry to affected gadgets, after which use these entry factors to achieve entry to different networks or compromise the supply, integrity, or confidentiality of information being transmitted from the inner community.”
Security researcher Brendan Scarvell has been credited with discovering and reporting the problems in October 2022.
In a associated growth, CERT/CC additionally detailed two unpatched safety vulnerabilities affecting TP-Link routers WR710N-V1-151022 and Archer-C5-V2-160201 that would result in data disclosure (CVE-2022-4499) and distant code execution (CVE-2022-4498).
CVE-2022-4499 can be a side-channel assault concentrating on a operate used to validate the entered credentials. “By measuring the response time of the susceptible course of, every byte of the username and password strings could also be simpler to guess,” CERT/CC stated.
Microsoft researcher James Hull has been acknowledged for disclosing the 2 bugs. The Hacker News has reached out to TP-Link for a remark, and we’ll replace the story if we hear again.
