CWE ID Description
CWE-190 The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Executive Summary

This vulnerability is an integer overflow or wraparound issue found in Dell PowerProtect Data Domain software versions 7.7.1.0 through 8.7, including specific LTS releases. An integer overflow occurs when a calculation exceeds the maximum size that can be stored in an integer variable, causing it to wrap around to a smaller value. This flaw can be exploited remotely by an unauthenticated attacker.

Exploitation of this vulnerability could lead to a denial of service condition, meaning the affected system could become unavailable or stop functioning properly.

Impact Analysis

If exploited, this vulnerability can cause a denial of service (DoS) on the affected Dell PowerProtect Data Domain system. This means that the system could become unresponsive or crash, potentially disrupting backup and data protection services.

Since the attacker does not require authentication and can exploit the vulnerability remotely, the risk of disruption is higher, especially if the system is exposed to untrusted networks.
