The Bluetooth Low Energy Secure Manager Protocol (SMP) implementation on Telink Semiconductor BLE SDK versions before November 2019 for TLSR8x5x through 3.4.0, TLSR823x through 1.3.0, and TLSR826x through 3.3 devices installs a zero long term key (LTK) if an out-of-order link-layer encryption request is received during Secure Connections pairing. An attacker in radio range can have arbitrary read/write access to protected GATT service data, cause a device crash, or possibly control a device's function by establishing an encrypted session with the zero LTK.
The discovered bug occurs due to improper handling of some of the HTTP request headers provided by the client. This could allow an attacker to remotely exploit GateManager to achieve remote code execution without any authentication required. If carried out successfully, such an attack could result in a complete security breach that grants full access to a customer’s internal network, along with the ability to decrypt all traffic that passes through the VPN.

An issue was discovered in dnaTools dnaLIMS 4-2015s13. dnaLIMS is vulnerable to a NUL-terminated directory traversal attack allowing an unauthenticated attacker to access system files readable by the web server user (by using the viewAppletFsa.cgi seqID parameter).

This vulnerability allows remote attackers to execute arbitrary code on affected installations of CentOS Web Panel cwp-e184.108.40.206.923. Authentication is not required to exploit this vulnerability. The specific flaw exists within ajax_ftp_manager.php. When parsing the userLogin parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-9737.
Security researchers at Claroty [published details](https://www.claroty.com/2020/07/28/vpn-security-flaws/) on multiple pre-auth remote code execution vulnerabilities affecting virtual private network (VPN) implementations primarily used to provide remote access to operational technology (OT) networks. The vulnerabilities could allow unauthenticated attackers to execute arbitrary code.
Individual CVEs referenced in Claroty's research include CVE-2020-14500, CVE-2020-14508, CVE-2020-14510, CVE-2020-14512, CVE-2020-14511, and CVE-2020-14498. Affected products include Secomea GateManager, Moxa EDR-G902/3 industrial VPN servers, and eWon by HMS Networks.
