Network device manufacturer Netgear has just patched a high-severity vulnerability impacting multiple WiFi router models. The flaw, tracked as CVE-2022-48196, is described as a pre-authentication buffer overflow security vulnerability, which, if exploited, could allow threat actors to carry out a number of malicious activities. These activities include stealing sensitive information, creating Denial-of-Service (DoS) conditions, as well as downloading malware and executing arbitrary code. In past attacks, threat actors have utilized this type of vulnerability as an initial access vector by which they pivot to other parts of the network. Currently, there is very little technical information regarding the vulnerability and Netgear is temporarily withholding the details to allow as many of their users to update their vulnerable devices to the latest secure firmware. Netgear stated that this is a very low-complexity attack, meaning that unsophisticated attackers may be able to successfully exploit a device. CTIX analysts urge Netgear users with any of the vulnerable devices listed in Netgear’s advisory to patch their device immediately.
