Analysis

Impact

An integer overflow or wraparound flaw (CWE-190) exists in Dell PowerProtect Data Domain. The vulnerability arises from improper handling of integer values, allowing a remote attacker to influence internal numeric calculations. Successful exploitation can terminate or otherwise disrupt the services, effectively denying availability to legitimate users.

Affected Systems

PowerProtect Data Domain versions 7.7.1.0 through 8.7, the LTS2026 release series 8.6.1.0 through 8.6.1.10, the LTS2025 release series 8.3.1.0 through 8.3.1.30, and the LTS2024 release series 7.13.1.0 through 7.13.1.70 are impacted by this integer overflow.

Risk and Exploitability

The CVSS score of 6.5 indicates moderate severity. The EPSS score of < 1% indicates a very low probability of real-world exploitation, and the vulnerability is not listed in the CISA KEV catalog. Based on the description, the likely attack vector is remote unauthenticated access, and an attacker could trigger a service interruption by manipulating integer values in the data path.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
