AlienVault OTX Vulnerabilities

AlienVault OTX Malware

An exploitable firmware downgrade vulnerability was discovered on the Netgear WPN824EXT WiFi Range Extender. An attacker can conduct a MITM attack to replace the user-uploaded firmware image with an original old firmware image. This affects Firmware 1.1.1_1.1.9 and earlier.

CVE-2022-38956 is a firmware downgrade vulnerability affecting the Netgear WPN824EXT WiFi Range Extender, specifically impacting firmware versions 1.1.1_1.1.9 and earlier. The vulnerability allows an attacker to perform a Man-in-the-Middle (MITM) attack during the firmware update process. By intercepting the firmware upload, the attacker can replace the user-uploaded firmware image with an older, original firmware version. This downgrade attack can reintroduce previously patched vulnerabilities or weaker security controls, thereby compromising the device's integrity. The vulnerability is classified under CWE-354, which relates to improper protection against MITM attacks. The CVSS v3.1 base score is 5.3 (medium severity), with the vector indicating network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), no confidentiality impact (C:N), high integrity impact (I:H), and no availability impact (A:N). No known exploits are currently reported in the wild, and no official patches or vendor advisories are linked in the provided data. The attack requires the victim to initiate a firmware update and the attacker to be positioned to intercept the communication, which may be feasible in local network environments or compromised network segments. The main risk is that downgraded firmware may contain exploitable flaws, enabling attackers to gain unauthorized control or disrupt device functionality.
