Overview
CVE-2025-30099 is a high-severity vulnerability affecting Dell PowerProtect Data Domain systems, specifically those running the Data Domain Operating System (DD OS). This vulnerability is of paramount concern due to its potential to allow low privileged attackers to execute arbitrary commands with root privileges on the affected systems, thereby leading to total system compromise or data leakage.

How the Exploit Works
The exploit takes advantage of an OS command injection vulnerability within the DDSH CLI component of the DD OS. By injecting malicious commands into the operating system, an attacker can bypass the system’s security measures. This occurs due to the system’s failure to properly neutralize special elements used in OS commands.
Conceptual Example Code
Below is a conceptual example of how the OS command injection vulnerability might be exploited. Please note that this is a simplified pseudocode representation and the actual exploitation process would be complex and depend on the specific system configuration.
# Suppose 'input' is a parameter controlled by the attacker
input = "innocuous_command; malicious_command"
# The system would treat it as two separate commands
system.execute(input)In this example, `innocuous_command` is a legitimate command that the system allows, and `malicious_command` is the attacker’s arbitrary command executed with root privileges. The semicolon is a command separator in many systems, allowing multiple commands to be executed in sequence.
To mitigate this vulnerability, it’s recommended to apply vendor patches as soon as they become available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary protection. Despite these measures, the only comprehensive solution is to patch the system to neutralize the command injection vulnerability.
