Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
An issue was discovered on Mimosa Client Radios before 2.2.4 and Mimosa Backhaul Radios before 2.2.4. On the backend of the device's web interface, there are some diagnostic tests available that are not displayed on the webpage; these are only accessible by crafting a POST request with a program like cURL. There is one test accessible via cURL that does not properly sanitize user input, allowing an attacker to execute shell commands as the root user.
CWE-74 - Injection
Listed as the number one web application security risk on the 'OWASP Top Ten', injection attacks are widespread and dangerous, especially in legacy applications. Injection attacks are a class of vulnerabilities in which an attacker injects untrusted data into a web application that gets processed by an interpreter, altering the program's execution. This can result in data loss/theft, loss of data integrity, denial of service, and even compromising the entire system.
