How the Exploit Works
The vulnerability occurs due to improper neutralization of special elements that are used in an OS command within the Hyper-V component of Dell PowerProtect Data Manager. An attacker with low privilege and local access could potentially exploit this vulnerability by injecting malicious OS commands, which the system would then execute.
Conceptual Example Code
A hypothetical example of how the vulnerability might be exploited is shown below:
$ echo "; malicious_command" > /path/to/vulnerable/input/fileIn this example, the malicious command is appended after a semicolon to the vulnerable input file, which is processed by the vulnerable application. The semicolon allows the attacker to execute additional commands following the intended command, leading to OS command injection.
