IoT vulnerabilities

An authentication bypass in telnet server in BF-430 and BF431 232/422 TCP/IP Converter, BF-450M and SEMAC from CHIYU Technology Inc allows obtaining a privileged connection with the target device by supplying a specially malformed request and an attacker may force the remote telnet server to believe that the user has already authenticated.

An issue was discovered on Tenda AC11 devices with firmware through 02.03.01.104_CN. A stack buffer overflow vulnerability in /goform/setmac allows attackers to execute arbitrary code on the system via a crafted post request.

In IoT Devices SDK, there is an implementation of calloc() that doesn't have a length check. An attacker could pass in memory objects larger than the buffer and wrap around to have a smaller buffer than required, allowing the attacker access to the other parts of the heap. We recommend upgrading the Google Cloud IoT Device SDK for Embedded C used to 1.0.3 or greater.

A path traversal vulnerability in the web interfaces of Buffalo WSR-2533DHPL2 firmware version <= 1.02 and WSR-2533DHP3 firmware version <= 1.24 could allow unauthenticated remote attackers to bypass authentication.

D-Link DNS-320 FW v2.06B01 Revision Ax is affected by command injection in the system_mgr.cgi component, which can lead to remote arbitrary code execution.

Microsoft Defender Remote Code Execution Vulnerability

A vulnerability in Cisco IoT Field Network Director (FND) could allow an unauthenticated, remote attacker to view sensitive database information on an affected device. The vulnerability is due to the absence of authentication for sensitive information. An attacker could exploit this vulnerability by sending crafted curl commands to an affected device. A successful exploit could allow the attacker to view sensitive database information on the affected device.

An issue was discovered on D-Link DCS-2530L before 1.06.01 Hotfix and DCS-2670L through 2.02 devices. cgi-bin/ddns_enc.cgi allows authenticated command injection.

An issue was discovered on D-Link DCS-2530L before 1.06.01 Hotfix and DCS-2670L through 2.02 devices. The unauthenticated /config/getuser endpoint allows for remote administrator password disclosure.

TP-Link TL-WA855RE V5 20200415-rel37464 devices allow an unauthenticated attacker (on the same network) to submit a TDDP_RESET POST request for a factory reset and reboot. The attacker can then obtain incorrect access control by setting a new administrative password.

Some devices of Thales DIS (formerly Gemalto, formerly Cinterion) allow Directory Traversal by physically proximate attackers. The directory path access check of the internal flash file system can be circumvented. This flash file system can store application-specific data and data needed for customer Java applications, TLS and OTAP (Java over-the-air-provisioning) functionality. The affected products and releases are: BGS5 up to and including SW RN 02.000 / ARN 01.001.06 EHSx and PDSx up to and including SW RN 04.003 / ARN 01.000.04 ELS61 up to and including SW RN 02.002 / ARN 01.000.04 ELS81 up to and including SW RN 05.002 / ARN 01.000.04 PLS62 up to and including SW RN 02.000 / ARN 01.000.04

An issue was discovered in AvertX Auto focus Night Vision HD Indoor/Outdoor IP Dome Camera HD838 and Night Vision HD Indoor/Outdoor Mini IP Bullet Camera HD438. Failed web UI login attempts elicit different responses depending on whether a user account exists. Because the responses indicate whether a submitted username is valid or not, they make it easier to identify legitimate usernames. If a login request is sent to ISAPI/Security/sessionLogin/capabilities using a username that exists, it will return the value of the salt given to that username, even if the password is incorrect. However, if a login request is sent using a username that is not present in the database, it will return an empty salt value. This allows attackers to enumerate legitimate usernames, facilitating brute-force attacks. NOTE: this is different from CVE-2020-7057.

Guangzhou 1GE ONU V2801RW 1.9.1-181203 through 2.9.0-181024 and V2804RGW 1.9.1-181203 through 2.9.0-181024 devices allow remote attackers to execute arbitrary OS commands via shell metacharacters in the boaform/admin/formPing Dest IP Address field.

A malicious guest compromised before a container creation (e.g. a malicious guest image or a guest running multiple containers) can trick the kata runtime into mounting the untrusted container filesystem on any host path, potentially allowing for code execution on the host. This issue affects: Kata Containers 1.11 versions earlier than 1.11.1; Kata Containers 1.10 versions earlier than 1.10.5; Kata Containers 1.9 and earlier versions.

The Zephyr MQTT parsing code performs insufficient checking of the length field on publish messages, allowing a buffer overflow and potentially remote code execution. NCC-ZEP-031 This issue affects: zephyrproject-rtos zephyr version 2.2.0 and later versions.

In the Zephyr Project MQTT code, improper bounds checking can result in memory corruption and possibly remote code execution. NCC-ZEP-031 This issue affects: zephyrproject-rtos zephyr version 2.2.0 and later versions.

The MQTT protocol 3.1.1 requires a server to set a timeout value of 1.5 times the Keep-Alive value specified by a client, which allows remote attackers to cause a denial of service (loss of the ability to establish new connections), as demonstrated by SlowITe.

In the ioctl handlers of the Mediatek Command Queue driver, there is a possible out of bounds write due to insufficient input sanitization and missing SELinux restrictions. This could lead to local escalation of privilege with no additional execution privileges needed.

Comtrend VR-3033 DE11-416SSG-C01_R02.A2pvI042j1.d26m devices have Multiple Authenticated Command Injection vulnerabilities via the ping and traceroute diagnostic pages, as demonstrated by shell metacharacters in the pingIpAddress parameter to ping.cgi.

Multiple ZyXEL network-attached storage (NAS) devices running firmware version 5.21 contain a pre-authentication command injection vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable device. ZyXEL NAS devices achieve authentication by using the weblogin.cgi CGI executable. This program fails to properly sanitize the username parameter that is passed to it. If the username parameter contains certain characters, it can allow command injection with the privileges of the web server that runs on the ZyXEL device. Although the web server does not run as the root user, ZyXEL devices include a setuid utility that can be leveraged to run any command with root privileges. As such, it should be assumed that exploitation of this vulnerability can lead to remote code execution with root privileges. By sending a specially-crafted HTTP POST or GET request to a vulnerable ZyXEL device, a remote, unauthenticated attacker may be able to execute arbitrary code on the device. This may happen by directly connecting to a device if it is directly exposed to an attacker. However, there are ways to trigger such crafted requests even if an attacker does not have direct connectivity to a vulnerable devices. For example, simply visiting a website can result in the compromise of any ZyXEL device that is reachable from the client system. Affected products include: NAS326 before firmware V5.21(AAZF.7)C0 NAS520 before firmware V5.21(AASZ.3)C0 NAS540 before firmware V5.21(AATB.4)C0 NAS542 before firmware V5.21(ABAG.4)C0 ZyXEL has made firmware updates available for NAS326, NAS520, NAS540, and NAS542 devices. Affected models that are end-of-support: NSA210, NSA220, NSA220+, NSA221, NSA310, NSA310S, NSA320, NSA320S, NSA325 and NSA325v2

A stack buffer overflow vulnerability exists in the way MiniSNMPD version 1.4 handles multiple connections. A specially timed sequence of SNMP connections can trigger a stack overflow, resulting in a denial of service. To trigger this vulnerability, an attacker needs to simply initiate multiple connections to the server.

IBM Watson IoT Message Gateway 2.0.0.x, 5.0.0.0, 5.0.0.1, and 5.0.0.2 is vulnerable to a buffer overflow, caused by improper bounds checking when handling a failed HTTP request with specific content in the headers. By sending a specially crafted HTTP request, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause a denial of service. IBM X-Force ID: 174972.
