Microhard · Microhard Bullet-Lte · CVE-2020-17406
**Name of the Vulnerable Software and Affected Versions**
Microhard Bullet-LTE versions prior to 1.2.0-r1112
**Description**
This issue allows remote attackers to execute arbitrary code on affected installations. Authentication is required to exploit this issue. The flaw exists within the handling of the `ping` parameter provided to `tools.sh`, resulting from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this issue to execute code in the context of root.
**Recommendations**
For versions prior to 1.2.0-r1112, update to version 1.2.0-r1112 or later to resolve the issue. As a temporary workaround, consider restricting access to the `tools.sh` script and validating all user-supplied input to minimize the risk of exploitation. Avoid using the `ping` parameter in the affected `tools.sh` script until the issue is resolved.
