oFono SimToolKit Heap-based Buffer Overflow Privilege Escalation Vulnerability. This vulnerability allows local attackers to execute arbitrary code on affected installations of oFono. An attacker must first obtain the ability to execute code on the target modem in order to exploit this...

Astra Linux – Vulnerability in Zabbix

Zabbix allows for the configuration of SMS notifications. AT command injection occurs on the “Zabbix Server” because there is no validation of the “Number” field either on the web interface or on the Zabbix server side. An attacker can send specially crafted phone numbers via SMS and execute...

Astra Linux – Vulnerability in Zabbix

Setting the SMS media allows for setting the GSM modem file. This file is later used as a Linux device. But since everything is a file for Linux, it’s possible to set another file, such as a log file. In this case, Zabbixserver will attempt to communicate with it as a modem. As a result, the log...
